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 (π) rads and is decreasing at the rate of 0.50 rad/s, what is the magnitude of the emf induced in the loop? A) zero B) 13 mV C) 26 mV D) 20 mV E) 18 mV
