Question

a conducting loop of radius r is present in a uniform magnetic field b perpendicular to the plane of ring if ra





​

Answer 1

Explanation:

A conducting loop of radius R is present in a uniform magnetic field B perpendicular to the plane of the ring. If radius R varies as a function of time t, as R=R0+t. The emf induced in the loop is. Since area is increasing, induced emf is in anticlockwise sense to oppose the chang in flux.J
