Magnetic Glossary
1. Residual Induction, Br
Flux density, measured in gauss, of a magnetic material after being fully magnetized in a closed
circuit.
2. Maximum Energy Product, BHmax
The maximum product of (BdHd) which can be obtained on the demagnetization curve.
3. Intrinsic Coercive Force, iHc
Oersted measurement of the material¡¯s inherent ability to resist self-demagnetization.
4 Coercive Force, Hcb
The demagnetizing force, in oersteds, required to reduce the residual induction, Br, of a fully
magnetized magnet to zero.
5.Maximum Operating Temperature
The maximum temperature of exposure that a magnet can forego without significant long-range
instability or structural changes
6.Curie Temperature
Temperature at which a material loses its magnetic properties.
7.Gauss
Unit of measure of magnetic induction, B, or flux density in the CGS system.
8.Gaussmeter
instrument that measures the instantaneous value of magnetic induction, B. Its principle of
operation is usually based on one of the following: the Hall effect,nuclear magnetic resonance (NMR),
or the rotating coil principle.
9.Magnetic induction ,B
the Flux per unit area of a section normal to the direction of the magnetic path. Measured in gauss.
10.demagnetization curve
Also known as the BH Curve,It is the second (or fourth) quadrant of a major hysteresis loop. Points
on the normal curve are designated by the coordinates Bd and Hd.Generally describing the behavior
of magnetic characteristics in actual use.
