A 50-turn circular coil (radius = 15 cm) with a total resistance of 4.0Ω is placed in a uniform magnetic field directed perpendicular to the plane of the coil. The magnitude of this field varies with time according to B = A sin (wt), where the amplitude is A = 80μT and the angular frequency is w = 50π rad/s. What is the magnitude of the current induced in the coil at t = 20 ms?
