A circular coil with a radius of 20 cm and containing 60 turns is placed in a uniform magnetic field which makes an angle of 30 degrees with respect to the plane of the coil. The total resistance of the coil is 12 O. If the magnetic field decreases from 1.3 T to 0.5 T in a time of 1.2 s, find the magnitude and direction of the induced current in the coil.
