There are some notable specific kinds of the magnetic field. For the physics of magnetic materials, see
The electric field and the magnetic field are components of the electromagnetic field.
The law of electromagnetism was founded by
Physicists can say that the
In the magnetic pole model, the elementary magnetic dipole m is formed by two opposite magnetic poles of pole strength qm separated by a very small distance d, such that m = qm d.
Unfortunately, magnetic poles cannot exist apart from each other. All magnets have north/south pairs which cannot be separated without creating two magnets each having a north/south pair. Also, magnetic poles do not account for
