Electric Charges and Fields

Question

Predict the directions of induced currents in metal rings 1 and 2 lying in the same plane where current I in the wire is increasing steadily. 



Answer

The direction of induced current is predicted using Lenz’s law. So, current is induced in a direction so as to oppose the increasing magnetic flux.

Therefore, direction of current is clockwise in ring 1 and anticlockwise in ring 2.
