A circular loop of wire of resistance r = 0.500

A circular loop of wire of resistance R = 0.500 ohms and radius r = 8.00 cm is in a uniform magnetic field directed out of the page as in the figure below. If a clockwise current of I = 2.50 mA is induced in the loop, (a) is the magnetic field increasing or decreasing in time? (b) Find the rate at which the field is changing with time.
