Some points on Magnetism.
Some objects attract iron or steel are call magnets.

A magnet has a magnetic force field around it.

The force is either a push or a pull.

The force field is concentrated around the poles.

There are north and south poles.

The law of magnetism states that unlike poles will attract and like poles will repel.

When current flows through a conductor it creates a electromagnetic force field.
