A coil of 1000 turns encloses an area of 25 cm2. It is rotated in 0.010 s from a position where its plane is perpendicular to Earth’s magnetic field to one where its plane is parallel to the field. If the strength of the field is 6.0 x 10-5, what is the average emf induced in the coil?
a) 15 μV
b) -15mV
c) 15mV
d) 0V
