the uniform magnetic field perpendicular to the plane of a conducting ring of radius a change at the rate of alpha , then

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

A conducting ring is placed in a uniform magnetic field with its plane perpendicular to the field . An emf is induced in the ring if

A conducting ring is placed in a uniform magnetic field with its plane perpendicular to the field . An emf is induced in the ring if

A planar loop of wire rotates in a uniform magnetic field. Initially at t =0, the plane of the loop is perpendicular to the magnetic field. If it rotates with a period of 10 s about an axis in its plane, then the magnitude of induced emf will be maximum and minimum, respectively at
