A50-turn circular coil (radius = 15 cm) with a total resistance of 4.0 ω is placed in a uniform magnetic field directed perpendicularly to the plane of the coil. the magnitude of this field varies with time according to b = a sin (αt), where a = 80 μt and α = 50π rad/s. what is the magnitude of the current induced in the coil at t = 20 ms?
