- [Voiceover] We're already looked at
Faraday's law in some detail.
It showed us that if we have some
loop of conductor and we have a change
in magnetic flux over
time through the surface
defined by that loop, it's going to induce
an EMF through that loop which will cause
a current to start to
circulate through that loop
and that current, of
course, will be dependent
on the actual resistance of the conductor.
And there's many ways
that we've already seen
of having a change in magnetic flux.
One, you can have a change
in the magnetic field.
It could be a change in its magnitude
and, or it's orientation.
You could have a change in the shape
of the actual loop of conductor.
If its area increases or decreases,
that will change the flux.
Remember, the flux is just your,
the component of the magnetic field
that is perpendicular to the surface.
If you took the average of that times
the area of the surface.
And then the other way that we're going

Bulgarian: 
Вече разгледахме
закона на Фарадей
с някои подробности.
Той ни показа, че ако имаме
 затворен проводящ контур
и имаме промяна в магнитното 
поле през времето
през повърхността,
ограничена от този контур,
това ще индуцира електродвижеща сила (EMF)
през тази верига,
поради което ще започне 
протичане на ток
през този контур.
Този ток, разбира се,
ще зависи
от реалното съпротивление
на проводника.
И има много начини,
по които вече сме виждали,
че може да има
промяна в магнитния поток.
Първо, може да имаш
промяна в магнитното поле.
Това може да е промяна
в големината му
и/или в ориентацията му.
Може да имаш
промяна във формата
на проводящия контур.
Ако площта се увеличи
или намалее,
това ще промени потока.
Помни, потокът е просто –
компонентата на
магнитното поле,
която е перпендикулярна
на повърхността.
Ако вземеш средната стойност на това
по площта на повърхността.
И, после, другият начин,
който ще изучаваме в това видео,

Czech: 
Faradayův zákon už jsme
probrali do hloubky.
Víme, že máme-li vodivou smyčku,
jejíž plochou prochází
magnetický tok proměnlivý v čase,
bude se v ní indukovat
elektromotorické napětí,
které v ní vyvolá proud
závislý na odporu vodiče.
Viděli jsme mnoho způsobů,
jak změnu magnetického toku zajistit.
Zaprvé je to změna magnetického pole.
Můžeme měnit jeho velikost
nebo orientaci.
Můžeme měnit samotný tvar smyčky.
Pokud je její plocha zmenší nebo zvětší,
změní se tok skrz ní.
Pamatujte, tok je pouze složka
magnetického pole kolmá k povrchu smyčky.
Berete jeho průměr
a násobíte jej plochou smyčky.

Thai: 
เราได้ดู
กฎของฟาราเดย์ไปบ้างแล้ว
มันบอกเราว่า ถ้าเรามี
วงตัวนำไฟฟ้า และเรามีการเปลี่ยนแปลง
ฟลักซ์แม่เหล็กเมื่อเวลาผ่านไป ที่ทะลุผ่านผิว
ที่กำหนดโดยลูปนั้น มันจะเหนี่ยวนำ
EMF ผ่านลูปนั้น ซึ่งทำให้เกิด
กระแสไหลวนรอบลูปนั้น
และกระแสนั้น แน่นอน จะขึ้นอยู่กับ
ตัวต้านทานจริงของตัวนำไฟฟ้านั้น
และมันมีวิธีทำให้เกิด
การเปลี่ยนแปลงฟลักซ์แม่เหล็กหลายวิธี
หนึ่ง คุณเปลี่ยนสนามแม่เหล็กได้
มันเป็นการเปลี่ยนแปลงขนาด
หรือการวางตัวของมันก็ได้
คุณมีการเปลี่ยนแปลงรูปร่าง
ของวงตัวนำก็ได้
ถ้าพื้นที่ของมันเพิ่มหรือลด
มันจะเปลี่ยนฟลักซ์
นึกดู ฟลักซ์ก็คือ
องค์ประกอบของสนามแม่เหล็ก
ที่ตั้งฉากกับผิว
ถ้าคุณนำค่าเฉลี่ยของมันคูณ
พื้นที่ผิว
แล้วสิ่งที่เราจะศึกษา

English: 
to study in this video is
inducing an electromotive force
by changing it, not the shape of the loop
and not the magnetic field but by changing
the orientation of the loop.
And in particular, we're
going to have the loop rotate.
So let's think about this.
So I have this loop here.
It's connected to this axle
and I'm going to rotate it
in a, I'm going to rotate
it in a clockwise direction
through this constant magnetic field.
You can see it's constant.
All of the magnetic field vectors
I've just sampled'em at
different points in the field.
They're all pointing straight
up and I've drawn them
so that they all have the same magnitude.
Now we'd appreciate is as we rotate this,
the angle between the magnetic field
and the surface is changing
and right from this point,
as we rotated this clockwise direction,
the component of the magnetic field
that is perpendicular to the
surface is going to increase.
Now what am I talking about?
Well, let's look at it
from this point of view.
Let's look at it from the point of view
of the actual loop of wire,
so from this point of view

Thai: 
ในวิดีโอนี้ คือการเหนี่ยวนำแรงเคลื่อนไฟฟ้า
โดยการเปลี่ยน ไม่ใช่รูปร่างของลูป
หรือสนามแม่เหล็ก แต่เป็นการเปลี่ยน
การวางตัวของลูป
โดยเฉพาะการให้ลูปหมุน
ลองคิดเรื่องนี้ดู ผมมีลูปนี่ตรงนี้
มันเชื่อมกับแกนหมุน และผมจะหมุนมัน
ผมจะหมุนมันแบบตามเข็มนาฬิกา
ผ่านสนามแม่เหล็กคงที่นี้
คุณเห็นได้ว่ามันคงที่
เวกเตอร์สนามแม่เหล็กทั้งหมด
ผมแค่สุ่มวาดจุดต่างๆ ในสนาม
พวกมันชี้ขึ้นตรงหมด และผมวาดมัน
ให้พวกมันมีขนาดเท่ากันหมด
ทีนี้ เราจะเข้าใจมันเมื่อเราหมุนวงนี้
มุมระหว่างสนามแม่เหล็ก
กับผิวจะเปลี่ยนไป และจากจุดนี้
เมื่อเราหมุนลูปนี้ในทิศตามเข็มนาฬิกา
องค์ประกอบของสนามแม่เหล็ก
ที่ตั้งฉากกับผิวนี้จะเพิ่มขึ้น
ผมกำลังพูดถึงอะไร?
ลองดูมันจากมุมมองนี้
ลองดูมันจากมุมมอง
ของวงสายไฟ จากมุมมองนี้

Bulgarian: 
е индуциране на
електродвижеща сила
чрез променяне
не на формата на контура
и не на магнитното поле,
а чрез променяне на
ориентацията на контура.
И по-точно контурът
ще се върти.
Нека помислим за това.
Тук имам този контур.
Свързан е с тази ос
и ще го завъртя
в посока по
часовниковата стрелка
през това постоянно
магнитно поле.
Можеш да видиш,
че е постоянно.
Всички вектори
на магнитното поле,
просто ги избрах в
различни точки от полето.
Те сочат право нагоре
и съм ги начертал така,
че да имат
една и съща дължина.
Сега ще видим,
че докато въртим това,
ъгълът между
магнитното поле
и повърхността
се променя
и от тази точка, докато въртим
в тази посока по часовниковата стрелка,
компонентата на магнитното поле,
която е перпендикулярна на повърхността,
ще се увеличи.
За какво говоря?
Нека го разгледаме
от тази гледна точка.
Нека го разгледаме
от гледната точка
на самия проводящ контур,
от тази гледна точка

Czech: 
V tomto videu se podíváme na další způsob,
jak indukovat elektromotorické napětí,
kdy nebudeme měnit magnetické pole ani
tvar smyčky, ale její orientaci.
Konkrétně ji budeme otáčet.
Zamysleme se nad tím.
Mám tuhle smyčku.
Je připojená na tuhle osu
a já s ní budu otáčet
po směru hodinových ručiček
v tomto konstantním magnetickém poli.
Vidíte, že je konstantní.
Všechny vektory magnetického pole,
kterými jsem jej znázornil,
míří přímo vzhůru
a mají stejnou velikost.
Když tímhle začneme otáčet,
bude se měnit úhel mezi
magnetickým polem a plochou smyčky.
Když tím pootočíme
ve směru hodinových ručiček,
složka magnetického
pole kolmá k ploše se zvětší.
O čem to mluvím?
Podívejme se na to takto.

Bulgarian: 
магнитното поле
е под някакъв ъгъл.
Мога да начертая този ъгъл,
какъвто и да е този ъгъл тук,
малко е трудно да се види,
какъвто и да е този ъгъл тук,
можем да кажем,
че е този ъгъл тук
и да кажем, че докато въртим целия контур,
това е прикрепено към някакъв вид ос тук,
в посока по
часовниковата стрелка,
какво ще се случи
с този ъгъл?
След, да кажем, делта t,
да кажем, че въртим
с постоянна скорост,
ще имаме магнитното...
след като сме въртели с малко,
векторът на
магнитното поле
ще изглежда
ето така.
Това е компонентата,
която е перпендикулярна на повърхността –
тя ни интересува
при потока –
това ще се промени
от изглеждащо така
до изглеждащо
ето така.
Поне за тази точка
на въртене,
за тази точка на въртене,
докато стигнем до плоската точка,
докато контурът стане
напълно плосък,

English: 
the magnetic field is at some angle.
I can draw that angle here
so, you know, whatever angle,
it's a little hard to see,
whatever angle this is,
we could say that is that angle here
and as we rotate the
entire loop, it's attached
to some type of an axle here,
in a clockwise direction.
What is going to happen to this angle?
Well, after let's say delta
T, let's say we're just
rotating it a constant
rate, we're going to have
the magnetic, so after
we've rotated a little bit,
the magnetic field of vector is going
to look something like that.
So it's the component
that is perpendicular
to the surface was what
we care about for flux,
it's going to go from being
like this, it's gonna go
from being like that to going to being,
to being like this, to being like this.
So at least for this
point of the rotation,
for this point of the rotation till we get
to the flat, until we
get to the flat point,
until we have our loop
being completely flat,

Thai: 
สนามแม่เหล็กจะทำมุม
ผมวาดมุมนั้นได้ คุณก็รู้ มุมนั้น
มันดูยากหน่อย ไม่ว่ามุมนั้นเป็นเท่าใด
เราบอกได้ว่ามันคือมุมตรงนี้
และเมื่อเราหมุนทั้งวงนั้น มัน
ติดกับแกนหมุนสักอย่างตรงนี้ 
ในทิศตามนาฬิกา
แล้วจะเกิดอะไรขึ้นกับมุมนี้?
หลังจาก สมมุติว่าเดลต้า t สมมุติเรา
หมุนมันด้วยอัตราคงที่ เราจะได้
แม่เหล็ก หลังจากที่เราหมุนไปเล็กน้อย
เวกเตอร์สนามแม่เหล็กจะ

Czech: 
Z hlediska smyčky je magnetické pole
skloněno pod nějakým úhlem.
Můžu ten úhel nakreslit sem.
Je to prostě nějaký úhel.
Není tu moc dobře vidět.
Řekněme, že je tady.
Když otáčíme touto smyčkou
ve směru hodinových ručiček,
co se s tímto úhlem bude dít?
Po nějakém čase delta T,
když tím otáčíme konstantní rychlostí…
Když tím trochu pootočíme,
magnetické pole bude vypadat takto.
Toku se týká jenom složka kolmá k povrchu,
která se změní z této podoby na tuto.
Takže aspoň pro tuhle fázi otočení,
než bude smyčka ve vodorovné poloze,

이 각을 델타라고 합시다
일정한 속도로 회전시키면

Bulgarian: 
компонентата на магнитното поле,
която е перпендикулярна,
ще се увеличи,
така че през това време ще имаме
увеличение в потока.
Ако имаме увеличение на потока
през това време,
докато въртим нагоре, поне докато
стигнем до тази равна точка,
какво ще се случи?
Ще индуцираме ток
и после просто трябва
да определим
каква е ориентацията
на тока.
Искаме да имаме
ток,
който ще индуцира
магнитно поле,
което ще бъде срещу
промяната в потока,
така че токът трябва
да индуцира магнитно поле, което е...
ако нашият поток, поне за
тази част от въртенето,
се увеличава в
посока нагоре,
ако сме от гледна точка
на тази верига,
тогава трябва да създадем
магнитно поле,
което действа
срещу това.
Магнитното поле,
което е обратно на това.
Или трябва...
ще индуцираме ток,
който индуцира магнитно поле,
което действа срещу
тази промяна в потока.
Какъв вид ток
ще индуцира такова
магнитно поле?
Ще използвам правилото
за дясната ръка,
пръстите ми преминават
в посоката на линиите

Czech: 
kolmá složka magnetického pole
se bude zvětšovat.
Magnetický tok se v tom čase
tedy bude zvětšovat také.
Máme-li nárůst toku v čase,
kdy otáčíme touto smyčkou
až do polohy, kdy je úplně naplocho,
co se bude dít?
Budeme indukovat proud
a zbývá jen zjistit jeho orientaci.
Chceme proud, který indukuje
magnetické pole jdoucí proti změně toku.
Pokud náš tok v této části otáčení
narůstá směrem vzhůru,
z hlediska této smyčky musíme vytvořit
magnetické pole působící proti tomu.
Indukujeme proud, který vytváří
magnetické pole potlačující změnu toku.
Jaký proud takové pole vytvoří?

Thai: 
องค์ประกอบของสนามแม่เหล็ก
ที่ตั้งฉากจะเพิ่มขึ้น
ซึ่งจะให้ เราจะได้
ฟลักซ์เพิ่มขึ้นตลอดช่วงเวลานั้น
ถ้าเรามีฟลักซ์เพิ่มขึ้นตลอดเวลานั้น
เมื่อเราหมุนขึ้น อย่างน้อยกระทั่ง
เราถึงจุดแบบราบ
มันจะเกิดอะไรขึ้น?
เราจะเหนี่ยวนำกระแส
แล้วเราต้องคิดว่า
การวางตัวของกระแสเป็นอย่างไร?
เราอยากได้กระแสที่
เหนี่ยวนำสนามแม่เหล็กที่
ต้านการเปลี่ยนแปลงฟลักซ์ กระแส
จึงเหนี่ยวนำสนามแม่เหล็ก
ถ้าฟลักซ์ของเรา อย่างน้อยในการหมุนส่วนนั้น
กำลังเพิ่มในทิศขึ้น
ถ้าเราเริ่มจากมุมมองของลูป
เราต้องสร้างสนามแม่เหล็ก
ที่ต้านการเพิ่มนั้น
สนามแม่เหล็กที่ต้านการเปลี่ยนแปลง
ที่เราต้องสร้าง เราเหนี่ยวนำกระแส
ที่เหนี่ยวนำสนามแม่เหล็กซึ่ง
ต้านการเปลี่ยนแปลงของฟลักซ์
ผมจะทำอย่างไร กระแส
ที่เหนี่ยวนำสนามแม่เหล็ก
อย่างนั้นเป็นอย่างไร?
ผมก็ใช้กฎมือขวา นิ้วผม
จะไปตามทิศสนาม

English: 
the component of our magnetic field
that is perpendicular is going to increase
which is going to have,
so we're going to have
an increase in flux over that time.
So if we have an increase
in flux over that time
as we rotate up, at least
until we get to the flat point,
what is going to happen?
Well, we're going to induce a current
and then we just have to think about what
is the orientation of the current?
So we want to have a current that
will induce a magnetic field that will
go against the change
in flux so the current
should induce a magnetic field that is,
if our flux, at least for
that part of the rotation
is increasing in the upwards direction,
if we're from the point
of view of this loop,
then we need to create a magnetic field
that is acting against that.
So magnetic field that
is acting against that
or we need to, we're
ready to induce a current
that induces a magnetic field that acts
against that change in flux.
So, how do I, what type of current
would induce a magnetic field like that?
So I'll just use the
right-hand rule, my fingers
would go in the direction of these,

пръстите ми – и ще трябва
да използвам дясната си ръка –
пръстите ми ще сочат

палецът ми ще сочи

Това ще е посоката на тока,
който е индуциран.
Цялата причина
да ти показвам това е,
че има множество начини
да имаме
промяна в
магнитното поле
и има множество начини
да индуцираме ток.
И това е
особено интересно,
понеже ти позволява –
или можем да започнем да мислим,
че мога да превърна едно
механично въртене
в индуциран ток
и това е основен принцип –
въпреки че те не могат
да използват такъв прост контур –
именно на този принцип работят
генераторите на електричество.
Те са, в определен смисъл,
обратното на един
електрически мотор.
В един електрически мотор
има ток,
който кара
нещо да се върти.
Тук нещо се върти,
което води до образуване на ток,

English: 
of the magnetic field, so my fingers
and I have to use my right hand,
so my fingers are gonna
go in that direction,
so my right hand, my thumb,
my thumb would go in this direction.
So that is going to be the direction
of the current that is induced.
So the whole point of me showing you this,
is that there's multiple ways to have
a change in magnetic flux and there's
multiple ways to induce a current.
And this one is particularly interesting
because it lets you or we
can start to think about,
wow, I could turn, I could
turn a mechanical rotation
into an induced current and
this is, this basic principle
although they wouldn't use
such a simple loop like this,
is exactly how electric generators work.
They're actually, in some ways,
the reverse of an electric motor.
An electric motor has a current
that causes something to rotate.
Here, we're having something rotate
causing a current to
form and that's actually
what we have happening when you look
at something like windmills or

Czech: 
Použiji pravidlo pravé ruky, moje prsty
půjdou ve směru magnetických siločar.
Musím použít svou pravou ruku,
takže moje prsty budou mířit tudy,
můj palec bude mířit tudy.
To tedy bude směr indukovaného proudu.
Ukazuji vám to, abyste si uvědomili,
že je mnoho způsobů,
jak způsobit změnu magnetického toku
a indukovat proud.
Tento způsob je obzvláště zajímavý,
protože díky němu můžeme
převést mechanické otáčení
na indukovaný proud!
Tento základní princip
je součástí skutečných generátorů,
i když ty nepoužívají jen
takhle jednoduchou smyčku.
Vlastně jsou opakem elektrických motorů.
Elektrický motor spočívá v tom,
že proud způsobuje otáčivý pohyb.
Tady otáčivý pohyb způsobuje proud.

Bulgarian: 
или хидроелектрически генератори.
Тук при тази
вятърна мелница
вятърът ще накара тези перки
да се въртят,
а вътре в това
малко място тук
ще имаш по-сложна
версия на контура, която се върти,
и това ще
индуцира ток.
Магнитното поле няма
да е точно така.
То ще има по-сложен
механизъм,
но основният принцип
е същият.
Това е просто
законът на Фарадей.
Същото нещо важи при
хидроелектрическия генератор –
използваш потенциалната енергия
на течащата вода,
за да завъртиш
една ос,
а после това ти помага
да генерираш електричество
чрез точно същия принцип.

English: 
when you look at hydroelectric generators.
Right over here, this windmill, the wind
is going to cause these
blades to turn around
and then inside, inside
of this little place
right over here, you're going
to have a more fancy version
of this rotating which is
going to induce a current.
The magnetic field isn't
going to be exactly like this.
It's going to be a more
sophisticated mechanism
but it's the same underlying principle.
It's just Faraday's law at work.
Same thing with hydroelectric generator,
you're using the potential energy
of the flowing water to turn an axle
and then that helps us
generate electricity
by the exact same principle.

수력 발전에서 사용됩니다

Tohle se děje ve větrných

U této větrné elektrárny
vítr otáčí lopatkami

máte trochu lepší verzi této smyčky,
která se otáčí a generuje proud.
Magnetické pole nevypadá úplně takto.
Mechanismus je vylepšený,
ale základní princip je stejný.
Uplatňuje Faradayův zákon.
U vodní elektrárny je to stejné.
Vyzužíváte potenciální energie

ที่ซับซ้อนขึ้น ซึ่งเหนี่ยวนำกระแสขึ้นมา
สนามแม่เหล็กจะไม่ได้เป็นแบบนี้ซะทีเดียว
มันจะมีกลไกซับซ้อนกว่า
แต่หลักการเบื้องหลังนั้นเหมือนกัน
มันก็แค่กฎของฟาราเดย์ในทางปฏิบัติ
เช่นเดียวกับเครื่องกำเนิดไฟฟ้าพลังน้ำ
คุณใช้พลังงานศักย์
ของน้ำไหลไปหมุนแกน
แล้วช่วยให้เราสร้างไฟฟ้า
ด้วยหลักการเดียวกันได้
