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 [..]

The result of plotting the value of the magnetic field (H) that is applied against the resultant flux density (B) achieved. This curve describes the qualities of any magnetic material. A graphic expla [..]

The Maximum Energy Product at the point on the B/H Curve that has the most strength, expressed in MGOe (MegaGaussOersteds). When describing the grade of a neodymium magnet, this number is commonly ref [..]

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 demagnetizing force, measured in Oersteds, necessary to reduce observed induction, B, to zero after the magnet has previously been brought to saturation.

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

The second quadrant of the hysteresis loop, generally describing the behavior of magnetic characteristics in actual use. Also known as the B-H Curve. Find these curves for some of our most popular mag [..]

A magnetizing force, typically in the direction opposite to the force used to magnetize it in the first place. Shock, vibration and temperature can also be demagnetizing forces.
