Homopolar generator. A spoked, conducting wheel rotates in an ac magnetic field as shown in Figure 10.44. The frequency of rotation is ω rad/s. The magnetic field intensity is H = 10 = 6 cos(ωt) [WA/m]
(a) Calculate the induced voltage between the center of the wheel and its outer perimeter.
(b) How does the solution change if the wheel is a solid conducting wheel?
