A magnet having a preferred direction of magnetic orientation.
Coercive force, Hc
The demagnetizing force, measured in Oersteds necessary to reduce the induction, B to zero after a magnet has been previously saturated.
Curie temperature, Tc
The transition temperature above which a material looses its magnetic properties.
The condition existing in a material subjected to magnetizing force. The unit of flux is the Maxwell.
Lines of magnetic flux per square centimeter. This is a measure of flux density.
The magnetic flux per unit area of a section normal to the direction of flux. This is measured in Gauss.
Intrinsic Coercive Force, Hci
This is a measure of a materials ability to resist demagnetization. This is measured in Oersteds.
This is defined as the partial demagnetizing of a magnet caused by external factors.
A magnet material whose magnetic properties are the same in any direction.
Magnetic Field strength, H
A measurement of the magnetic ability to induce a magnetic field at a given point. This is measured in Oersteds.
The total magnetic induction over a certain area.
Magnetizing Force, H
The magnetomotive force per unit length at any point in the magnetic circuit. this is measured in Oersteds.
Magnetomotive Force, F
The magnetic potential difference between any two points.
A unit of magnetic flux. One Maxwell is one line of magnetic flux.
A unit of magnetic field strength or magnetizing force.
The direction in which an anisotropic magnet should be magnetized in order to optimize the magnetic properties.
This is a condition where all magnetic moments have become oriented in one direction.
Exposing a magnet to demagnetizing influences which are expected in the application in order to prevent irreversible loss during the operation of the magnet.
