A circular ring of radius r is placed in a homogeneous magnetic field perendicular to the plane of the ring. The field B changes with time according to the equation B=kt where K is constant and r is the time. The electric field in the ring is:

The magnetic field perpendicular to the plane of a conducting ring of radius r changes at the rate. (dB)/(dt) . Then

A conducting ring of radius r is placed perpendicular inside a time varying magnetic field as shown in figure. The magnetic field changes with time according to B = B_0 + alphat where B_0 and alpha are positive constants. Find the electric field on the circumference of the ring.

A conducting ring of radius r and resistance R is placed in region of uniform time varying magnetic field B which is perpendicular to the plane of the ring. It the magnetic field is changing at a rate alpha , then the current induced in the ring is
