(b)
A rectangular coil of 20 turns with dimensions 8 cm x 6 cm sides is held
perpendicular to the uniform magnetic field, with half the area of the loop in the field, as
shown the following figure. The loop contains an ideal battery with emf & = 1.5 V. The
magnitude of the magnetic field varies with time according to B = – 4t2 + 3t + 3.0 , with B
in teslas and tin seconds.
(a) Calculate the magnitude and direction of the emf induced around the loop at t = 15 sec.
(b) Find the net current with appropriate direction in the loop at t = 15 sec if the loop has a
resistance of 2 2.
