Amagnetic field is aligned perpendicular to the plane of a circular loop of wire with radius 5.0 cm and 20 turns. the magnetic field b changes with time t according to the following function: b 12 exp(-3t) +1.5t +6 t determine the induced emf in the circular loop of wire as a (i) function of time, and the time at which the induced emf is 0.1 v. (ii) if the magnetic fieldis instead aligned at 30° with respect to the normal of the circular loop of wire, find the induced emf as a function of time.
