Question 218: Electromagnetic Induction

Question

A conducting ring of certain resistance is falling towards a current carrying straight long conductor. The ring and conductor are in the same plane. Then

Accepted Answer

The magnetic field produced by the currentcarrying straight wire will be directed outside the plane of the paper, within the conducting ring. As the ring falls toward the conductor, the magnetic flux through the ring will continuously increase. According to Lenz's Law, the induced current will oppose the change in magnetic flux. Therefore, the induced current in the ring will flow in a direction (clockwise) that opposes the increasing magnetic flux. Thus, the current in the conducting ring will be induced in a clockwise direction.

Answer

induced current in the coil is zero.

Answer

induced current in the coil is anticlockwise.

Answer

induced current in the coil is clockwise.

Answer

ring will come to rest.
