A rectangular loop of area A is placed in a region where the magnetic field is perpendicular to the plane of the loop. The magnitude of the field is allowed to vary in time according to B = Bmaxe-t/r, where Bmax and r are constants. The field has the constant value Bmax for t < 0.
(a) Use Faraday’s law to show that the emf induced in the loop is given by
(b) Obtain a numerical value for Є at t = 4.00 s when A = 0.160 m2, Bmax = 0.350 T, and r = 2.00 s.
(c) For the values of A, Bmax, and - given in (b), what is the maximum value of Є?
