Question
A square loop (length along one side = 20 cm) rotates in a constant magnetic field which has a magnitude of 2 T. At an instant when the angle between the field and the normal to the plane of the loop is equal to 10° and increasing at the rate of 10°/s, what is the magnitude of the induced emf in the loop?
a) E = - 13.8 mV
b) E = 3.61 mV
c) E = - 20.7 mV
d) E = 2.42 mV
e) E = 20.7 mV
E = 13.8 mV
