A circular loop of 80 turns with a radius of 15.0 cm is perpendicular to a magnetic field of 0.52 T. How much-induced voltage is created if it is rotated in 0.20s so that its face is parallel to the field?

Answer:
A 50-turn coil has a diameter of 15 cm. The coil is placed in a spatially uniform magnetic field of magnitude 0.50 T so that the face of the coil and the magnetic field are perpendicular. Find the magnitude of the emf induced in the coil if the magnetic field is reduced to zero uniformly in (a) 0.10 s, (b) 1.0 s, and (c) 60 s.
