Question: A flat, circular, steel loop of radius 75 cm is at rest in a uniform magnetic field, as shown in an edge-on view in Fig.

A flat, circular, steel loop of radius 75 cm is at rest in a uniform magnetic field, as shown in an edge-on view in Fig. 29.28. The field is changing with time, according to B (t) = (1.4T)e -(0?057 B-1)t.(a) Find the emf induced in the loop as a function of time.(b) When is the induced emf equal to 1/10 of its initial value?(c) Find the direction of the current induced in the loop, as viewed from above theloop.
