Consider a metal ring kept on top of a fixed solenoid (say on a carboard) The centre of the ring coincides with the axis of the solenoid. If the current is suddenly switched on then

Consider a metal ring kept on top of a fixed solenoid (say on a cardboard) as per figure. The centre of the ring coincides with the axis of the solenoid. If the current is suddenly switched on, the metal ring jumps up. Explain.

Consider a metal ring kept on the top of a fixed solenoid (say on a cardboard) (Fig. EP 6.14). The centre of the ring coincides with the axis of the solenoid. If the current is suddenly switched on, the metal ring jumps up. Explain.

Consider a metal rign kept on top of fixed solenoid carrying a current as shown in the figure . The centre of the ring coincides with the axis of the solenoid. If the current is suddenly switched off, what will happen to the ring?

Consider a metal ring kept (supported by a cardboard) on top of a fixed solenoid carrying a current I as per figure. The centre of the ring coincides with the axis of the solenoid. If the current in the solenoid is switched off, what will happen to the ring ?

A metal ring kept (supported by a card borad) on the top of a fixed soleniod carry a current I as shown in figure. The center of the ring coincides with the axis of the solenoid. If the current in the soleniod is switched off, then

Consider metal ring kept on a horizontal plane . A bar magnet is held above the ring with its length along the axis is held above the ring with its length along the axis of the ring . If the magnet is dropped freely the acceleration of the falling magnet is : ( g is accelration due to gravity )

The diagram given below shows a solenoid carrying time varying current l= l_(0)t . On the axis of the solenoid, a ring has been placed. The mutual inductance of the ring and the solenoid is M and the self inductance of the ring is L. If the resistance of the ring is R then maximum current which can flow through the ring is
