Question

A loop of wire enclosing an area S is placed in a region where the magnetic field is perpendicular to the plane. The magnetic field B varies with time according to the expression B=B_0e^(-at) where a is some constant. That is, at t= 0. The field is B_0 and for t gt 0, the field decreases exponentially. Find the induced emf in the loop as a function of time.

Answer 1

Answer:

the field is B0 and therefore the field decease exponentially
