So a rectangular loop is being pulled into a constant magnetic field which is directed into the pace.
00:05
We have to find a direction of the induced current while it is moving and only probably partially in the magnetic field.
00:12
Okay.
00:12
So remember the lenses law.
00:14
The lenses law always suggests the lens is law, lens law always suggests that the induced emf, induced emf is in the direction.
00:28
Induced emf opposed cause.
00:35
What is the cause? cause is the change of flux.
00:38
What is the change in the flux is because of the increasing magnetic field because as soon as the area which is inside the magnetic field is increasing, definitely the net magnetic field inside this loop is increasing, right? so in order to decrease it, the induced current should be such that it should oppose this magnetic field.
00:58
And that is only possible when it will be in clockwise sense.
01:02
Because if it will be in clockwise sense, then using the right hand rule, we curl our fingers towards the current and the thumb actually gives the direction of the magnetic fee...
