A plane circular disk of radius 0.25m rotates at a speed of 200 rad/s about an axis through the center of the disk perpendicular to the plane of the disk. There is a uniform magnetic flux B = 1 Tesla parallel to the axis of rotation. Calculate the emf between the center of the disk and its rim. This is called a homopolar generator.
