Glossary
- Anisotropic Magnet
- 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.
- Flux
- The condition existing in a material subjected to magnetizing force. The
unit of flux is the Maxwell.
- Gauss
- Lines of magnetic flux per square centimeter. This is a measure of flux
density.
- Induction, B
- 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.
- Irreversible Loss
- This is defined as the partial demagnetizing of a magnet caused by
external factors.
- Isotropic magnet
- 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.
- Magnetic Flux
- 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.
- Maxwell
- A unit of magnetic flux. One Maxwell is one line of magnetic flux.
- Oersted, Oe
- A unit of magnetic field strength or magnetizing force.
- Orientation Direction
- The direction in which an anisotropic magnet should be magnetized in
order to optimize the magnetic properties.
- Saturation
- This is a condition where all magnetic moments have become oriented in
one direction.
- Stabilization
- Exposing a magnet to demagnetizing influences which are expected in the
application in order to prevent irreversible loss during the operation of
the magnet.
