Magnet Glossary
Anisotropic |
Magnet material having a preferred direction of magnetic orientation |
Bonded Magnets |
Magnet powders mixed with polymer carrier; mechanical properties reach from elastic to hard; penalty of bonded material is a "weaker magnet" compared to non-bonded material |
Coercivity Hc [kA/m] |
Demagnetizing force necessary to reduce polarisation J (HcJ) or induction B (HcB) to zero |
Curie Temperature |
Temperature at which a magnet is totally demagnetized |
Energy Product BH max [kJ/m3] |
Point on the second quadrant of the hysteresis loop at which the product of induction B and magnetizing force H reaches a maximum; describes the "strength" of magnet material |
Gauss |
Unit of magnetic flux density in the CGS system (1 Gauss = 10-4 Tesla) |
Isotropic |
Magnet material with no preferred orientation; can be magnetized in any direction |
Magnet Pole |
"Output" of the magnetic flux |
Oersted |
Unit of magnetizing force in the CGS system (1 Oersted = 0.0796 kA/m) |
Remanence Br [mT] |
Residual induction in magnet material after being magnetized to saturation |
Tesla |
Unit of magnetic flux density in the SI system (1mT = 10 Gauss) |
