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 the figure (Figure 1). The field is changing with time, according to B(t) = (1.4T)e-(0.057-1)t
Part A
Find the emf induced in the loop as a function of time (assume t is in seconds).
Part B
When is the induced emf equal to 1/10 of its initial value?
Part C
Find the direction of the currentt induced in the loop, as viewed from above the loop.
