A flat circular coil of 1 cm radius is rotated at 10 revolutions per second about an axis that is perpendicular to a uniform magnetic field of magnitude 2.5 T. How many turns are required in the coil to generate a peak voltage of 750 mV?
a.) 2 turns
b.) 5 turns
c.) 8 turns
d.) 15 turns
e.) 20 turns
peak voltage
e = N B A w
0.75 = N * 2.5*pi * 0.01^2* 10 2pi
N = 15 turns
