PHXII06:ELECTROMAGNETIC INDUCTION
358650
Two differents loops are concentric and lie in the same plane. The current in the outer loop is clockwise and increasing with time. The induced current in the inner loop is
1 Clockwise
2 Zero
3 Counter clockwise
4 In a direction that depends on the ratio of the loop radii
Explanation:
The induced current will be in such a direction so that it opposes the change due to which it is produced.

According to Lenz's law of electromagnetic induction
1 Only the magnet should be moved towards coil
2 The relative motion between the coil and magnet produce change in magnetic flux
3 Only the coil should be moved towards magnet
4 The induced e.m.f. is not in the direction opposing the change in magnetic flux
Explanation:
The relative motion between the coil and the magnet produces change in the magnetic flux in the coil and the induced emf is always in such a direction that it opposes the changes in the flux.

A metallic ring is attached with the wall of a room. When the north pole of a magnet is brought near to it, the induced current in the ring will be (seen from the magnet side)
1 In clockwise direction
2 First clockwise then anticlockwise
3 First anticlockwise then clockwise
4 In anticlockwise direction
Explanation:
As it is seen from the magnet side induced current will be anticlockwise.
