Electrical energy

Explanation:

An electromagnet produces mechanical energy from electrical energy. This process is termed electromagnetic induction.

In electromagnetism, electricity are generated using magnets.

Electromagnetic induction is the process by which electricity are generated using magnets. This can be done by bringing the a coil closer to a stationary magnet or bringing a magnet close to a stationary coil.

The amount of current produced depends on the strength of the magnet, the number of turns on the coil, the distance between the magnet and the coil (the smaller the distance the greater the amount of current produced and vice versa).

Note that for current to be generated, the magnet and the coil must be moving relative to each other but not both stationary at the same time.
