Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Every material is influenced to some extent by a magnetic field.
More about the magnetosphere. But what is magnetism? Until 1821, only one kind of magnetism was known, the one produced by iron magnets.
A simple introduction to magnetism, electromagnetism, and some of the things we can use them for.
Connection between magnetism and electricity.
In physics, magnetism is a force that can attract (pull closer) or repel (push away) objects that have a magnetic material like iron inside them (magnetic objects). In simpler words it is a property of certain substances which pull closer or repel other objects.
Magnetism is also associated with elementary particles, such as the electron, that have a property called spin.
Magnetism, along with electricity, belongs to a larger phenomenon, electromagnetism, or the force generated by the passage of an electric current through matter.

The force known as magnetism is caused by the motion of electrons. As these tiny, negatively charged particles revolve around an atomic nucleus...
Magnetism is one aspect of the combined electromagnetic force.
