Question

A circular loop (area = 0.20 m2) turns in a uniform magnetic field with B = 0.13 T. At an instant when the angle between the magnetic field and the normal to the plane of the loop is (p) rads and is decreasing at the rate of 0.50 rad/s, what is the magnitude of the emf induced in the loop?
Select one:
a. 18 mV
b. 20 mV
c. 26 mV
d. 13 mV
e. zero
