Define electromagnetic unit of current.

Define electromagnetic wave.

A thin diamagnetic rod is placed vertically between the poles of an electromagnet . When the current in the electromagnet is switched on , then the diamagnetic rod is pushed up , out of the horizontal magnetic field . Hence the rod gains gravitational potential energy . The work required to do this comes from
