A circular loop of radius a is located in the y-z plane center at the origin in the presence of a uniform B field pointed in the +x direction. At t=0 the loop is rotated counter clockwise with radial frequency about the z-axis.
1. Find the expression for the induced emf as a function of time, in terms of the given parameters.
2. Compare this emf with what would be induced in a rectangular loop of the same area
