Hello everyone.
00:02
So here we are given this problem where we have a bar magnet which is falling towards the center of this loop of wire where north pole of the bar magnet is facing the loop while south pole is obviously at the other end.
00:21
If the observer is looking from this side, then we have to find the direction of the induced current on this loop.
00:29
That is whether it's clockwise or anti -clockwise.
00:32
So let us start with the solution.
00:37
In such cases, we use a law called lensis law that says that the direction of induced current in this loop will be such that it will oppose the motion of this magnet.
00:52
That is if it is going in the downward direction, then induced current will be such that it will oppose its downward motion.
01:01
Now we know that for the lines of forces, this.
01:06
Start from north pole and terminate to south pole.
01:10
But here, according to lenses law, if it's going in downward direction, then the current will be induced in such direction that it will go in upward direction...
