A Rectangular Loop (Area = 0

Multiple Choice

A rectangular loop (area = 0.15 m²) turns in a uniform magnetic field with B = 0.20 T. At an instant when the angle between the magnetic field and the normal to the plane of the loop is (π/2) rad and increasing at the rate of 0.60 rad/s, what is the magnitude of the emf induced in the loop?

A) 24 mV
B) zero
C) 18 mV
D) 20 mV
E) 6.0 mV
