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. E29.8. The field is changing with time, according to B1t2 = 11.4 T2e-10.057 s-1 2t . (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 the loop
