A conducting ring is placed around the core of an electromagnet as shown in fig. when key `K` is pressed, the ring

A

Remain stationary

B

Is attracted towards the electromagnet

C

Jumps out of the core

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
C
Since, induced current is opposite to original current direction.
`therefore` Repulsive force will be there on the ring.

A closed conducting ring is placed in between two bar magnets as shown in the figure. The pole strength of M_1 is double that of M_2 . When the two bar magnets are at same distance from the centre of the ring, the bar magnet M_1 has given a velocity 2v while M_2 is given velocity v in the direction as shown in the figure. The direction of induced current in the ring as seen from XX from this moment to the moment till bar magnets collide is
