What are the phenomena?

Magnetism is a class of physical phenomena that are mediated by magnetic fields.  Ancient people found out that permanent magnets can attract iron filings.  They understood the phenomena between permanent magnets (attractive force between same poles while repulsive force between opposite poles of magnets).  A magnet exerts its magnetic field to its surrounding.  A magnetic field comes from a permanent magnet or a moving charged particle or electric current in a conductor.  Electric current produces electric field while a magnet produces magnetic field.

A magnetic field is a type of invisible and untouchable special matter.  Magnetic moments of particles give rise to a magnetic field, which acts on other currents and magnetic moments.  Every material is affected to some extent by a magnetic field to its surrounding.
