    Assume a rotating (angular velocity W) metal disk located in the x-y plane with a constant magnetic field B perpendicular to the disk.

    A circuit containing a resistor is connected between the spindle (axis) the disk rotates on and a spring contact that is in contact with the outer edge of the disk.

    What is the current flowing through the circuit?

    Please explain reasoning and show equations used to solve.
