A rectangular loop of wire is immersed in a non-uniform and time-varying magnetic field. The magnitude of the field is given by B = 4t2x2 , where t is the time in seconds and x is one dimension of the loop. The direction of the field is always perpendicular to the plane of the loop. The loop extends from x = 0 to x = 3.0 m and from y = 0 to y = 2.0 m. What is the magnitude of the induced emf in the loop at t = 0.10 s?
(a) 12 V
(b) 14 V
(c) 16 V
(d) 18 V
(e) 20 V
The answer is (b), I just do not understand how to solve this problem. Thanks!
