here today
properties around us
I am a firm believer
as well find many things just don't add
up the perceptions and observations
cannot match any model Yeah so Am I
obvious things showing clear and simple
examples everyday I tried to inspire to
push the boundaries of idea and
discovery and I suggest anyone listening
to this video
anyone even thinking of making a
contribution
and i really be totally don't have the
time thank you for taking the time to
hear me oh I wish everyone well world
order to I was making the point here
with this closed surface that when when
you have caused services is always going
normally out of the service or
perpendicular to the surface so if you
have a line coming in like this going
through this prior to this little da
here is negative because you're da is
word that way so the angle between those
two vectors is 180 degrees so if you
take the cosine of a hundred and eighty
degrees that gives you a negative one
basically the way it's going in as
negative and the lines coming out is
positive and then this is gonna be
straight across for you see that walks
through that he is just going straight
like that and this da has no flux
through it
this the DA's that have the most looks
through it or this guy and this guy in
terms of magnitude and the least boxes
this guy can you imagine it being 3d
there'd be another one here on the other
side that would have no flux ok but what
if this is a radiating this way what if
it's going like this like that
well it turns out that for every year
that goes in there be an arrow that
comes out and so the total blocks here
is still there
the way you can get you might say how
can you were here
situation where there is any flags it
seems like every line that goes in the
BLM that comes out well in
electrostatics and gravity the way you
do that if you put your math
charged in here charged in here that
charge will lines will start like that
and those laid out and so then you do
have a Netflix do their thing with
another search closer clothes put a
massive hear that man there's going to
be filled going in and so we have been
going in and they get a magnetic field
is closed loops they never start or
begin anywhere they always are closed
loops at least so far that we have found
and so because of that wherever I would
drive in service whether it's right here
these are closed agassi and services are
always close and I'll make them Spears
because they're easy but they could be
cubes or any other type of clothes
service Adelaide going to enter to the
amount allowed coming out or to the
total webber's is gonna be 0 going to
total flux that's true if I put my
service here to the Margazhi in circuses
are imaginary so if you're wondering how
much of it went in there that in fact
the magnet I gotta do is imagine if you
can't have any land go in let's see
123456 how many lights come out 123456
so the total amount of lines of magnetic
fluxes is
partial to the amount of wines that are
going out going into know then that
satellite's going into that although the
lines going out
magnetic field lines they 20 you might
think what if I were to break the magnet
and get rid of the South Pole so what if
I only had one call here kind of like
having just one charge good point then
maybe you would be able to hear all the
lines may be going out or something but
here's the thing is when you break I
magnin have you just created by cut this
in here you create a South a new south
and a new North fall so you will always
have a north wind itself there now find
a magnetic monopole just one poll that
this might be broken but for right now I
don't think they have found what could
be wrong and that you might do a search
and Google to figure out if that's the
case but for this course at least you
can assume that the you can assume that
this will always be the case that the
closed surface integral of be da da
that's the net flux through a closer
will always be zero in this course
please
