An example of Electro-magnetism

Use an Iron Core

Wrap more coils of wire

Add more current to the Electro Magnet

Electo-magnetism involves electrically charged particles. The process of Electro-Magnetism is when an electrically charged particle interacts with another which then causes an Electro-magnetic field

An electric is a good example of Electro-Magnets in use. A bell works with the two wires being connected to a power supply. The bell magnetises causing the spring near the striker to magnetise. It then pushes the striker to hit the bell
