The circular, conducting, disk shown in Figure lies in the x − y plane and rotates with uniform angular velocity ω about the z-axis. The disk is of radius a and is present in a uniform magnetic flux density B = ẑB0. Obtain an expression for the emf induced at the rim relative to the center of the disk.
