English: 
- [Voiceover] In other
videos we talk about
how a current flowing through a wire
can induce a magnetic field.
And we're going to talk
about in this video
is how we can go the other way.
How a change in a magnetic field
can affect or induce a current
in a loop of wire.
So we're gonna be going from a change,
change in and actually we're gonna
focus on magnetic flux.
Magnetic flux through a loop.
Through a loop.
And we're going to see how this
actually induces a current in that loop.
So it induces a current.
Induced current.
So this right over here,
and this is my attempt at
drawing a magnetic field,
and these are the magnetic field lines.
They don't look like lines because
they're all popping out of the screen.
They're moving towards
you, towards the viewer,

Czech: 
Zatím jsme mluvili o tom,
jak proud protékající vodičem
může indukovat magnetické pole.
V tomto videu se budeme bavit
o opačném jevu.
Jak změna magnetického pole může ovlivnit
či indukovat proud ve vodivé smyčce.
Budeme pozorovat změny magnetického toku.
Magnetický tok smyčkou.
Uvidíme, že to ve smyčce indukuje proud.
Tohle je můj pokus o nakreslení
magnetického pole.
Tohle jsou siločáry magnetického pole.
Nevypadají jako čáry,
protože vystupují ven z obrazovky.

Chinese: 
在从前的视频中我们讨论过流过电线的电流
能够产生感应磁场
在这个视频中我们会讲到
它的反定则
磁场的改变如何在闭合电路中影响或感生电流
我们现在要从（磁场的）改变着手
实际上我们先来关注一下磁通量
闭合电路里的磁通量

Thai: 
ในวิดีโอที่แล้ว เราพูดถึง
วิธีที่กระแสที่ไหลผ่านสายไฟ
เหนี่ยวนำสนามแม่เหล็กได้
ตอนนี้ สิ่งที่เราจะพูดถึงในวิดีโอนี้
คือสิ่งที่เราทำกลับกันได้
ว่าการเปลี่ยนแปลงของสนามแม่เหล็ก
มีผลหรือเหนี่ยวนำกระแส
ในวงสายไฟได้อย่างไร
เราจะไปจากการเปลี่ยนแปลง
การเปลี่ยนแปลงของ ที่จริง เราจะเน้น
ไปที่ฟลักซ์แม่เหล็ก
แม่เหล็ก
ฟลักซ์แม่เหล็กผ่านวง
ผ่านลูป
ตอนนี้เราจะเห็นว่ามัน
เหนี่ยวนำกระแสในลูปนั้นอย่างไร
เหนี่ยวนำ
เหนี่ยวนำกระแส
กระแสเหนี่ยวนำ
อันนี้ตรงนี้
ตรงนี้ นี่คือภาพที่ผมพยายาม
วาดสนามแม่เหล็ก
และพวกนี้คือเส้นสนามแม่เหล็ก
พวกมันดูไม่เหมือนเส้น
เพราะพวกมันพุ่งออกจากหน้าจอ
พวกมันเคลื่อนที่เข้าหาคุณ เข้าหาคนดู

Bulgarian: 
В други видеа
говорим за това
как ток,
протичащ през проводник,
може да създаде
магнитно поле.
В това видео
ще говорим
как можем да
направим обратното.
Как една промяна
в едно магнитно поле
може да повлияе на, или индуцира,
ток в затворен кръг от проводник.
Ще преминаваме
от промяна в –
и ще се фокусираме върху
магнитния поток.
Магнитен поток
в затворен контур.
Сега ще видим
как това
индуцира ток
в този затворен контур.
Индуцира ток.
Индуциран ток.
Това тук е опитът ми
да начертая едно магнитно поле
и това са линиите
на магнитното поле.
Не изглеждат
като линии,
понеже изскачат
от екрана.
Движат се към теб,
към зрителя,

Thai: 
คุณจะเห็นพวกนี้เป็นหัวลูกศร
ทีนี้ มันมีวิธีแสดงสนามแม่เหล็กวิธีอื่นๆ
คุณแสดงเส้นสนามแม่เหล็กแบบนี้ได้
คุณใช้เวกเตอร์ได้เช่นกัน
และเมื่อคุณใช้เส้นสนาม
มันคือความหนาแน่นของเส้นสนาม
บอกคุณว่าสนามแม่เหล็กเข้มแค่ไหน
ถ้าคุณไปตรงนี้
พวกมันหนาแน่นน้อยกว่า สนามแม่เหล็ก
จะเข้มน้อยกว่าทางขวาตรงนี้
เทียบกับทางซ้าย
หรืออย่างน้อย นั่นคือสิ่งที่ผมพยายามวาด
ทีนี้ ถ้าเราทำกับเวกเตอร์
เราจะได้ลูกศรใหญ่ขึ้นชี้ออกตรงนี้
เทียบกับที่เรามีตรงนี้
แต่ตอนนี้ ลองวาดลูป
ลองสร้างวงสายไฟกัน
ขอผมวาดวงสายไฟตรงนี้นะ
สมมุติว่าผมมีวงสายที่
นี่คือวงสายไฟ
วงสายไฟของผม
ถ้าผมโยนวงสายไฟเข้าไป
และถ้ามันอยู่กับที่ มันอยู่ในสนามแม่เหล็กนี้
และสนามแม่เหล็กไม่เปลี่ยน
ผมจะมีฟลักซ์ทะลุผ่าน
คุณจะเรียกว่าพื้นผิวที่กำหนดจากสายนี้ก็ได้
และถ้าคุณไม่คุ้นกับคำว่าฟลักซ์แม่เหล็ก

Bulgarian: 
тоест можеш да гледаш на това
като на върхове на стрелата.
Има различни начини
да показваме магнитните полета.
Можеш да покажеш линиите
на магнитните полета ето така,
можеш също
да използваш вектори.
И когато използваш
линии на полето,
плътността на линиите
на полето
ти показват колко силно
е магнитното поле.
Ако дойдеш тук
надясно,
те са не толкова плътни,
така че магнитното поле
е по-слабо в дясната страна тук,
отколкото вляво –
поне това се опитвам
да изобразя.
Ако го направим
с вектори
ще имаме по-големи стрелки,
сочещи навън, тук,
отколкото тук.
Но нека направим
един затворен контур.
Ще начертая
един проводник тук.
Да кажем, че имам
един затворен контур –
това е моят проводник.
Ако просто сложа
този затворен контур
и ако той е неподвижен,
той е в това магнитно поле
и магнитното поле
не се променя,
имам някакъв поток,
преминаващ през
повърхността, определена
от този проводник.
Ако не познаваш термина
магнитен поток,

English: 
so you can view these as
the tips of the arrow.
And there's different ways
of showing magnetic fields.
You could show magnetic
field lines like this.
You could also use vectors.
And when you're using field lines,
it's the density of the field lines
tell you how strong the magnetic field is.
So if you go to the right
here, they are less dense.
And so the magnetic field is less strong
on the right-hand side over here
than they are on the left-hand side,
or at least that's what
I'm trying to depict.
Now if we did it with vectors,
we would have a bigger arrows pointing out
over here than we would over there.
But now let's do a loop of,
let's do a loop of wire.
So let me draw a loop of wire here.
So let's say I have a
loop of wire that is,
so this is my loop of wire.
My loop of wire.
So if I just throw that loop of wire,
and it it's just stationary,
it's in this magnetic field,
and the magnetic field isn't changing,
I do have some flux
going through the I guess
you could say the surface
defined by this wire,
and if you're unfamiliar
with the term magnetic flux,

Czech: 
Směřují k vám, pozorovatelům,
měli byste je vidět jako špičky šipek.
Jsou různé způsoby
zobrazení magnetických polí.
Můžete použít takovéto siločáry,
ale také vektory.
Při použití siločar záleží síla
magnetického pole na jejich hustotě.
V tomto místě nejsou tolik nahuštěné,
takže magnetické pole je napravo slabší,
než tady nalevo.
Nebo se to tak aspoň snažím zobrazit.
Kdybychom kreslili vektory,
tady bychom měli delší šipky než tuhle.
Ale teď udělejme smyčku drátu.
Tohle je moje vodivá smyčka.
Pokud ji pouze položím do tohoto pole
a ono se nebude měnit,
budu mít nějaký tok plochou,
který tento drát ohraničuje.

Korean: 
따라서 화살표의 끝부분이
보인다고 생각하면 됩니다
전기장을 나타내는
여러 방법이 있는데
이 그림처럼
나타낼 수도 있고
벡터를 사용하여
나타낼 수도 있습니다
그리고 자기력선을
사용할 때는
선들의 밀도가
자기장의 세기를
나타냅니다
그림의 오른쪽에서는
선들의 밀도가 작으므로
자기장은 왼쪽에서보다
오른쪽에서의 세기가 더 작습니다
이 그림이 자기장의
세기를 알려줍니다
만약 벡터로 나타냈다면
오른쪽에서의 화살표가
왼쪽보다
더 크게 그려졌을 것입니다
이제 고리 도선을
그려보겠습니다
이제 고리 도선을
그려보겠습니다
('고리'는 끊이지 않고
한 바퀴 돌아가는 모양을 뜻함)
('고리'는 끊이지 않고
한 바퀴 돌아가는 모양을 뜻함)
(따라서 꼭 원형이 아니어도 됨)
 
이곳에 고리 도선을
두었을 때
도선이 자기장 안에
고정되어 있고
자기장이 변화하는
상태가 아니라면
이 도선으로 인해
정의된 평면을 지나는
자속이
존재할 것입니다
'자속'이라는 말이
익숙하지 않다면

English: 
I encourage you to watch
the video on magnetic flux.
But if I just have this wire stationary
in the magnetic field
nothing is going to happen.
But I will be able to induce a current
if I change the magnetic flux
going through this surface in some way.
So for example, right
now the magnetic field
is pointing out of the screen.
If I were to make it even stronger
than the direction
pointing out of the screen,
so I guess one way to think about it is
if the change in the magnetic field,
the change in the flux were to get
even stronger in the outward direction,
so I don't know a good way to,
so it's gonna get even stronger
in the outer direction,
I'll draw a big arrow there,
I guess you could say that these things
became even denser in
this outward direction,
it is actually going to induce a current.
And the current that it will induce
is going to go in that direction.
And now let me draw a little bit clearer.
The current is going to
go in that direction.

Czech: 
Pokud vám magnetický tok nic neříká,
podívejte se na video o něm.
Pokud se tenhle drát v magnetickém
poli nepohybuje, nic se nebude dít.
Proud se mi podaří indukovat
jen pokud nějakým způsobem změním
magnetický tok touto plochou.
Například teď magnetické
pole míří ven z obrazovky.
Kdybych ho v tomto směru ještě zesílil…
Představte si, že změním pole tak,
aby jeho tok směrem ven byl ještě silnější.
Nevím, jak to dobře znázornit…
Nakreslím sem velkou šipku.
Mohli bychom říct,
že tyto čáry směrem ven zhoustly.
To bude indukovat proud.
Indukovaný proud bude téct tímto směrem.
Nakreslím to trochu lépe.
Proud bude téct tímto směrem.

Bulgarian: 
окуражавам те да гледаш
видеото за магнитния поток.
Но ако просто
имам този проводник,
и той стои неподвижно
в магнитното поле,
нищо няма
да се случи.
Но ще мога
да индуцирам ток,
ако променя
магнитния поток,
преминаващ през тази повърхност,
по някакъв начин.
Например, сега магнитното поле
сочи навън от екрана.
Ако го направя
още по-силно
в посоката, която
сочи навън от екрана –
предполагам, един начин
да разглеждаме това, е, че
ако променя
магнитното поле,
промяната в потока ще стане
още по-силна
в посока навън.
Не знам,
добър начин...
просто ще стане още по-силен
в посока навън.
Тук ще начертая
голяма стрелка.
Предполагам можеш да кажеш,
че тези неща
стават още по-плътни
в посока навън.
Това ще индуцира ток.
И токът, който ще индуцира,
ще се движи в тази посока –
нека го начертая
малко по-ясно.
Токът ще тече
в тази посока.

Korean: 
자속에 관련된 영상을
보고 오는 것을 추천합니다
만약 이 도선을
자기장 안에
고정시키면
아무런 일도 일어나지
않을 것입니다
하지만 이 표면을
통과하는 자속을
어떻게든 변화시킨다면
전류를 유도시킬 수
있을 것입니다
예를 들어
현재 자기장은
화면을 뚫고
나오고 있습니다
이 자기장을
더 강력하게 만들 수
있다면 어떨까요?
한가지 방법은
화면 바깥 방향으로의
자기장에
변화를 주어
자속을 더 강력하게
하는 것입니다
그림으로 나타내기는
애매하지만
바깥방향으로
더욱 강력해지므로
큰 화살표를
그려보겠습니다
이것들이 바깥 방향으로
밀도가 조금 더
높아진다고 할 수도 있겠습니다
이는 전류를
유도시킬 것이고
유도된 전류는
이 방향이 될 것입니다
이 방향이 될 것입니다
 

Thai: 
ผมแนะนำให้คุณดูวิดีโอเรื่องฟลักซ์แม่เหล็ก
แต่ถ้าผมมีสายนี้
อยู่กับที่ในสนามแม่เหล็ก
มันจะไม่มีอะไรเกิดขึ้น
แต่ผมสามารถเหนี่ยวนำกระแส
ถ้าผมเปลี่ยนฟลักซ์แม่เหล็ก
ผ่านผิวนี้ทางใดทางหนึ่ง
ตัวอย่างเช่น ตอนนี้สนามแม่เหล็ก
ชี้ออกจากหน้าจอ
ถ้าผมทำให้มันเข้มขึ้น
ในทิศที่ชี้ออกจากหน้าจอ
ผมว่า วิธีคิดอย่างหนึ่ง
คือถ้าผม ถ้าการเปลี่ยนแปลง
ของสนามแม่เหล็ก
การเปลี่ยนแปลงของฟลักซ์นั้นเข้มขึ้น
ในทิศออก
ไม่รู้สิ วิธี
มันเข้มขึ้นในทิศออก
ผมจะวาดลูกศรใหญ่ตรงนี้
ผมว่า คุณจะเรียกว่า
สนามพวกนี้หนาแน่นขึ้นในทิศออกนี้
มันจะเหนี่ยวนำกระแสได้
และกระแสที่มันจะเหนี่ยวนำนั้น
จะไปในทิศนั้น
ขอผมวาดมันให้ชัดขึ้นหน่อย
กระแสจะไปในทิศนั้น

English: 
It's going to go in a clockwise
direction around this.
And that is because that change
in the magnetic flux
that induces a voltage,
an electro mode of force
that causes this current to flow,
And there's other ways to
change the magnetic flux.
If I were to lessen the magnetic field
in the outward direction or another way,
if the change in the
magnetic field were inwards,
then the current would
go the other direction.
But the key here is when I change the flux
through this surface defined by this wire,
it's going to induce a current.
The current isn't going to be there
if the magnetic field is stationary
and I'm not changing this loop in any way,
but as soon as I change
the flux in some way,
I am going to induce a current.
I could also, instead
of changing the field,
I could actually move my coil,
I could move it that way.
And if I were to move it that way,
the flux going through this surface,

Korean: 
도선을 따라
시계 방향이 될 것입니다
전류가 흐르는 이유는
자속의 변화가
전압을 유도했기 때문이고
전압은 전류를 만들어내는
전기적 원동력이기 때문입니다
 
자속을 바꾸는
다른 방법들도 있습니다
바깥쪽이든 어느쪽이든
자기장을 약화시키면
만약 안쪽으로
자기장을 변화시키면
만약 안쪽으로
자기장을 변화시키면
전류는 반대 방향으로
흐를 것입니다
어쨌든 여기에서
도선으로 정의된 평면을
통과하는 자속에
변화를 주었을 때
전류가 유도된다는 것이
중요합니다
만약 자기장이 일정하고
도선에 변화를
주지 않는다면
전류는 유도되지
않을 것입니다
하지만 어떤 방법으로든
자속을 변화시킨다면
전류가 유도될 것입니다
자기장을 변화시키는 대신
도선을 이동시킬
수도 있습니다
이쪽 방향으로 움직이면
이쪽 방향으로 움직이면
이 표면을 통과하는 자속

Czech: 
Bude téct po směru hodinových ručiček.
Změna magnetického toku indukuje
elektromotorické napětí,
které uvádí tento proud do pohybu.
Existují jiné způsoby,
jak změnit magnetický tok.
Kdybych magnetické
pole mířící ven oslabil,
kdyby změna magnetického pole mířila
dovnitř, proud by tekl opačným směrem.
Klíčové je, že když změním tok
plochou ohraničenou tímto drátem,
bude to indukovat proud.
Ve stacionárním magnetickém
poli tu proud nebude,
a s touto smyčkou vůbec nic nedělám.
Ale jakmile jakkoli změním magnetický tok,
budu indukovat proud.
Kromě změny pole samotného
můžu taky pohnout smyčkou.
Můžu ji posunout tudy.

Thai: 
มันจะไปในทิศตามเข็มนาฬิการอบวงนี้
และนั่นเป็นเพราะการเปลี่ยนแปลง
ของฟลักซ์แม่เหล็ก
ที่เหนี่ยวนำโวลเตจขึ้นมา
แรงเคลื่อนไฟฟ้าที่ทำให้กระแสไหล
มันทำให้กระแสไหล
และยังมีวิธีเปลี่ยนฟลักซ์แม่เหล็กอีก
ถ้าผมทำให้สนามแม่เหล็กอ่อนลง
ในทิศออก หรือกลับทิศ
ถ้าการเปลี่ยนแปลงสนามแม่เหล็กเป็นทิศเข้า
กระแสจะไหลอีกทิศหนึ่ง
แต่ประเด็นสำคัญคือเมื่อผมเปลี่ยนฟลักซ์
ผ่านพื้นผิวที่กำหนดโดยสายไฟนี้
มันจะเหนี่ยวนำกระแส
กระแสจะไม่เกิดถ้า
ถ้าสนามแม่เหล็กอยู่กับที่
และผมจะไม่เปลี่ยนลูปนี้อยู่แล้ว
แต่เมื่อผมเปลี่ยนฟลักซ์นี้
ผมจะเหนี่ยวนำกระแส
แทนที่จะเปลี่ยนสนาม
ผมยังเลื่อนวงสายไฟได้
ผมเลื่อนมันไปทางนั้นได้
และถ้าผมเลื่อนมันแบบนั้น
ฟลักซ์ผ่านสนามนี้

Bulgarian: 
Ще се движи в посока по
часовниковата стрелка около това.
И това е, понеже тази промяна
в магнитния поток,
която индуцира напрежение,
електродвигателна сила,
накара този ток да тече.
Това кара тока да тече
и има други начини
да променим магнитния поток.
Ако намаля магнитното поле
в посока навън, или,
друг начин,
ако промяната в магнитното поле
беше навътре,
тогава токът ще се
движи в другата посока.
Но ключовото нещо тук е,
че когато променя потока
през тази повърхност,
определена от този проводник,
това ще индуцира ток.
Токът няма да го има,
ако магнитното поле е неподвижно
и не променям този контур
по никакъв начин.
Но веднага, когато променя
потока по някакъв начин,
индуцирам ток.
Също мога, вместо
да променям полето,
да преместя намотката си.
Мога да я преместя насам.
И ако я преместя насам,
потокът през
тази повърхност,

Thai: 
ที่ออกจากผิวนี้จะเพิ่มขึ้น
แต่ถ้าผมเลื่อนวงนี้ไปทางซ้าย
สนามแม่เหล็กจะหนาแน่นขึ้น
มันเข้มขึ้น มันจึงมีฟลักซ์
ผ่านพื้นที่นี่ตรงนี้
ถ้าคุณเลื่อนมันแบบนั้น
คุณจะมีกระแสแบบนี้
ทีนี้ ถ้าคุณเลื่อนมันอีกทาง
ถ้ามันเคยอยยูทางซ้าย 
และคุณเลื่อนไปแบบนั้น
มันจะเหนี่ยวนำกระแส
แต่ตอนนี้ เนื่องจากฟลักซ์น้อยลง
ในทิศออก
กระแสจะไปอีกทาง
ทีนี้ มันยังมีวิธีเปลี่ยนฟลักซ์อื่นอีก
คุณเปลี่ยนพื้นที่ของลูปนี้ได้
ถ้ามันทำมาจาก
สายไฟที่ยืดได้
ถ้าคุณเพิ่ม
ถ้าคุณเพิ่ม
ขอผมวาดมันแบบนี้
ถ้าคุณสามารถยืดมันได้
ยืดจนมัน
พื้นที่มันก็เพิ่มขึ้น
ถ้าคุณยืดมันออกได้
พื้นที่มันจะเพิ่มขึ้น
ซึ่งทำให้ฟลักซ์ในทิศ
ที่ออกจากจอจะเพิ่มขึ้นอีก
มันจึงเหนี่ยวนำ

Bulgarian: 
излизащ от тази повърхност,
ще се увеличи.
Понеже, ако преместя
това наляво,
магнитното поле
е по-плътно,
по-силно,
така че ще има
повече поток
през тази област тук.
Ако го придвижиш насам,
ще имаш ето такъв ток.
Ако го придвижиш
в другата посока,
ако това беше вляво
и го придвижиш в другата посока,
това също ще
индуцира ток,
но тъй като сега потокът
намалява в посока навън,
токът ще тече
в обратната посока.
Има и други начини
да променим потока.
Можеш да промениш
площта на контура,
ако беше направен от
някакъв, може би, разтеглив проводник.
Ако увеличиш това,
ако увеличиш...
Нека го начертая така.
Ако някак успееш
да го разтеглиш,
да го разтеглиш така,
че да съдържа –
реалната площ
се увеличава.
Ако успееш да
го разтеглиш,
така че реалната площ
да се увеличи,
това ще накара потока
в посока навън от екрана
да се увеличи
още повече

Korean: 
즉 표면을 뚫고 나오는 자속은
증가할 것입니다
왜냐하면
왼쪽으로 갈수록
자기장의 밀도는 커지고
세기가 강력해지기 때문에
이 면적을 통과하는
자속이 증가하기
때문입니다
따라서 만약
이쪽으로 이동시킨다면
역시 이와 같은
전류가 유도될 것입니다
만약 도선이
왼쪽에 위치했을 때
반대쪽 방향으로
도선을 움직인다면
역시 전류가
유도되겠지만
화면 바깥쪽 방향으로의
자속이
감소하기 때문에
반대 방향의 전류가
유도될 것입니다
자속을 변화시키는
또 다른 방법들도 있습니다
고리 도선의
면적을 변화시킬 수도 있습니다
만약 도선이
수축성이 있는
소재로 만들어졌다면
말입니다
도선 내부 고리의 면적을
증가시키면
도선 내부 고리의 면적을
증가시키면
 
도선을 늘여서
도선 내부의 면적이
증가된다면
도선 내부의 면적이
증가된다면
 
면적의 증가로 인해
화면을 뚫고 나오는
자속은 증가할 것이고
따라서 전류가
유도될 것입니다

English: 
or I guess coming out of
this surface, will increase.
Because if I move this to the left,
the magnetic field is denser,
I guess it's stronger,
so there will more flux
through this area here.
So if you move it that way,
you also would have a current like this.
Now if you moved it the other way,
if it was on the left-hand
side and you moved it that way,
it would also induce a current,
but now since the flux is lessening
in the outward direction,
the current would go in the other way.
Now there's other ways to change the flux.
You could actually change the area
of this actual loop if somehow it was made
out of some maybe stretchy wire somehow.
If you had increased,
let me draw it this way.
If you were somehow able to stretch it,
so it contains, so the
actual area increases,
if you were able to stretch it out
so that the actual area increases,
which would cause the flux in the out
of the screen direction
to increase even more,

Czech: 
Pokud to udělám,
tok touto plochou se zvětší.
Posunu-li ji doleva,
magnetické pole je hustější,
a když je silnější,
zvětší se i tok touto plochou.
Posunete-li ji tímto směrem,
vznikne vám proud jako tady.
Kdybyste ji posunuli tudy,
zleva doprava,
také by se indukoval proud,
ale protože tok směrem ven slábne,
proud by tekl opačným směrem.
Měnit tok jde ještě jinak.
Mohli byste měnit plochu této smyčky,
kdyby třeba byla z drátu,
který lze natahovat.
Nakreslím to takhle.
Kdyby se vám povedlo ji natáhnout,
aby se zvětšila její plocha,
způsobilo by to nárůst magnetického
toku ve směru z obrazovky,

Czech: 
a indukoval by se proud.
Tohle je základ indukce proudu
změnou magnetického toku.
V dalších videích se tím
budeme zabývat hlouběji,
tohle je základ Faradayova zákona.
V dalších videích si řekneme
nějaké vzorečky,
ale zatím nám jde jen o myšlenku,
že měním-li magnetický tok
procházející smyčkou drátu,
bude to v ní indukovat proud.

Korean: 
따라서 전류가
유도될 것입니다
결론적으로 전류를
유도함에 있어서
자속의 변화가
필수적이고
더 자세한 내용은
다른 영상들에서 다루겠습니다
이것이 패러데이 법칙의
기본이고
 
 
이 영상에서
중요한 것은
고리 도선이 있을 때
고리 도선을 통과하는
자속이 변화한다면
전류가 유도될 것이라는
사실입니다

Thai: 
ที่เหนี่ยวนำกระแสได้เช่นกัน
แนวคิดนี้เรื่องการเปลี่ยนแปลงฟลักซ์แม่เหล็ก
ที่เหนี่ยวนำกระแส นี่คือหลักสำคัญ
และเราจะลงรายละเอียดมากขึ้นในวิดีโอต่อไป
นี่คือหลักสำคัญของกฎฟาราเดย์
ฟาราเดย์
กฎของฟาราเดย์ (Faraday's Law)
และเราจะบอกเชิงปริมาณในวิดีโอต่อๆ ไป
มันก็แค่แนวคิดที่ว่า ถ้าผมมีลูปสายไฟ
และผมมีฟลักซ์แม่เหล็กเปลี่ยน
ผ่านลูปสายไฟ
มันจะเหนี่ยวนำกระแสในสายไฟนั้น

Bulgarian: 
и това също
ще индуцира ток.
Тази цялата идея за
промяната в магнитния поток,
индуциращ ток,
това е същността –
и ще се задълбочим в нея
в бъдещи видеа –
това е същността на
закона на Фарадей.
Законът на Фарадей.
И ще разгледаме това
количествено в бъдещи видеа,
но това е идеята,
че ако имам затворен контур
и имам променящ се
магнитен поток
през проводника,
това ще индуцира ток
в този проводник.

English: 
that also would induce the current.
And so this whole idea of a change
in magnetic flux inducing a current,
this is the essence and we'll go deeper
into it in future videos,
this is the essence of Faraday's Law.
Faraday's Law.
And we'll quantify this
more in future videos,
but it's just the notion
that if I have a loop of wire,
and I have a changing magnetic flux
through the loop of wire,
that is going to induce
a current in that wire.
