Comparing with ε(t) = ε0e-ct
ε0 = 0.122
(1/18)ε0 = 0.122/18
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. The field is changing with time, according to
ε(t) = 0.122e-(0.057)t
When is the induced emf equal to 1/18 of its initial value?
