A metal ring kept (supported by a card I board) on the top of a fixed solenoid carry a current I as shown in figure. The centre of the ring coincides with the axis of the solenoid. If the current in the solenoid is switched off, then
magnetic flux linked with the metal ring increases.
- current induced in the metal ring in clockwise direction.
- metal ring will not remain on the cardboard.
- both [a] and [b] are correct.
Answer
(D) both [a] and [b] are correct.
