Question

A rectangular coil lies flat on a horizontal surface. A bar magnet is held above the center of the coil with its south pole pointing down. If the magnet is dropped from this position, what is the direction of the induced current in the coil?

A circular coil lays flat on a horizontal table in a region where the magnetic field is straight up. The magnetic field is suddenly removed. When viewed from above, what is the direction of the current in the coil as the field is removed?

00:01 Solution of this question is according to the question a rectangular coil a rectangular coil lies flat flat on a horizontal surface and a bar magnet is half above the center of of coil with its south pole pole pointing down.
01:48 We know that the magnetic field lines originate from the north pole and end up at the south pole of the magnet.
01:57 So in the initial position of the magnet there would be a number of magnetic field lines passing through the coil and going up to the south pole of the magnet.
02:08 So when the magnet is dropped the number of magnetic field lines passing through the coils is less...
