# Electromagnetic Induction: Induced current in rotating disk

Not what you're looking for?

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.

##### Solution Summary

Induced current in a disk rotating a magnetic field is determined.
