Magnetic pole

each of the points near the extremities of the axis of rotation of the earth or another celestial body where a magnetic needle dips vertically.

Magnetosphere

the region surrounding the earth or another astronomical body in which its magnetic field is the predominant effective magnetic field.

Magnetic domain

A magnetic domain is region in which the magnetic fields of atoms are grouped together and aligned. In the experiment below, the magnetic domains are indicated by the arrows in the metal material. You can think of magnetic domains as miniature magnets within a material.

Ferromagnetic material

Ferromagnetic materials, such as iron, contain unpaired electrons, each with a small magnetic field of its own, that align readily with each other in response to an external magnetic field. This alignment tends to persists even after the magnetic field is removed, a phenomenon called hysteresis.

Magnetic force

Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.

Magnetic field

a region around a magnetic material or a moving electric charge within which the force of magnetism acts.
