A toroid having a rectangular cross section (a = 2.00 cm by b = 3.00 cm) and inner radius R = 4.45 cm consists of 500 turns of wire that carries a sinusoidal current I = Imax sin wt, with I = 51.5 A and a frequency f = @/27 = 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. .196 X Your response differs from the correct answer by more than 10%. Double check your calculations. V ) cos wt a R 1 1- 6 -1
