2. A circular coil with 30 turns of wire has a diameter of 2.00 cm. The total resistance of the coil is 0.350 Ω. An applied uniform magnetic field is directed upward, perpendicular to the plane of the coil.

a) If the magnetic field changes linearly from 0.000 T to 0.800 T in 0.500 s, what is the induced emf in the coil while the field is changing?

b) What is the magnitude and direction (CW or CCW when looked at from above the coil) of the induced current in the coil while the magnetic field is changing?
