Orientation Direction: The direction in which an anisotropic magnet should be magnetized in order to achieve optimum magnetic properties. Also known as the “axis”, “easy axis”, or” angel of inclination”.

Maximum Energy Product, BHmax: The point on the Demagnetization Curve where the product of B and H is a maximum and the required volume of magnet material required to project a given energy in its surroundings is a minimum. Measured in Mega Gauss Oerteds, MGOe.

Oerted, Oe: A cgs unit of measure used to describe magnetizing force. The English system equivalent is Ampere Turns per Inch, and the SI system’s is Ampere Turns per Meter.

Magnetomotive Force, F: Analogous to voltage in electrical circuits, this is the magnetic potential difference between any two points.

North Pole: That pole of a magnet which, when freely suspended, would point to the north magnetic pole of the earth. The definition of polarity can be a confusing issue, and it is ofen best to clearify by sing “north seeking pole” instead of “north pole” in specifications.

Magnetizing Force, H: the magnetomotive force per unit length at any point in a magnetic circuit. Measured in oerteds in the cgs system.
