A circular conducting coil with radius 3.40 cm is placed in a uniform magnetic field of 0.880 T with the plane of the coil perpendicular to the magnetic field. The coil is rotated 180° about the axis in 0.222 s.

(a) What is the average induced emf in the coil during this rotation?
(b) If the coil is made of copper with a diameter of 0.900 mm, what is the average current that flows through the coil during the rotation?
