What does electromagnetism really mean?

All electric charges possess an electric field around them.

When they move their charge interacts with both their own electric field and the electric fields due to any other charges.

Moving electric charges induce a magnetic field. We call this effect electromagnetism.

This field changes according to the movement of the charges concerned.

This distinguishes it from 'permanent magenetic' fields which do not change with movement (apart from moving bodily themselves with the magnet)

 

But as Genady says the term is also used in a more general manner to cover all matter electrical and magnetic.
