The magnetomotive force per unit of magnet length, measured in Oersteds (C.G.S.) or ampere-turns per meter (S.I). Maxwell - The C.G.S. unit for total magnetic flux, measured in flux lines per squa [..]

The "external" distance from one pole of the magnet to the other though a non-magnetic material (usually air).

An anisotropic material has different properties in different directions. For example, wood which has a grain is stronger in some one direction than another. Like wood, neodymium magnets are also anis [..]

Also called "Residual Flux Density".  The magnetic induction remaining in a saturated magnetic material after the magnetizing field has been removed.  This is the point at wh [..]

The temperature at which a magnet loses all of its magnetic properties.

The physical size of a magnet including any plating or coating.

A magnet consisting of a solenoid with an iron core, which has a magnetic field only during the time of current flow through the solenoid. Learn more in our Electromagnets article.

A material that either is a source of magnetic flux or a conductor of magnetic flux. Most ferromagnetic materials have some component of iron, nickel, or cobalt.

An instrument used to measure the instantaneous value of magnetic induction, B, usually measured in Gauss (C.G.S.). Also called a DC magnetometer.

The unit of magnetomotive force, F, in the C.G.S. system.
