A toroid having a rectangular cross section

(a = 2.00 cm

by

b = 3.00 cm)

and inner radius

R = 3.75 cm

consists of 500 turns of wire that carries a sinusoidal current

I = I_max sin(????t),

with

I_max = 46.0 A

and a frequency

f = ????/2???? = 60.0 Hz.

A coil that consists of 20 turns of wire links with the toroid, as shown in the figure. Determine the emf induced in the coil as a function of time.
