Anisotropic Magnet £ºA magnet having a preferred direction of magnetic orientation, so that the magnetic characteristics are optimum in one preferred direction¡£
(BH) max Maximum energy product, is the maximum product of (BdHd) which can be obtained on the demagnetization curve.
Br Residual induction (or flux density), is the magnetic induction corresponding to zero magnetizing force in a magnetic material after saturation in a closed circuit; measured in gauss.
Coercive Force(Hcb)£ºThe demagnetizing force, measured in Oersteds, necessary to reduce observed induction, B, to Zero after the magnet has previously been brought to saturation.
Curie Temperature(Tc)£¬The temperature at which the parallel alignement of elementary magnetic moments completely disappears, and the material is no longer able to hold magnetization.
Demagnetization Curve£¬The second quadrant of the hysteresis loop, generally describing the behavior of magnetic characteristics in actual use, also known as the B-H curve.
Gauss£ºLines of magnetic flux per square centimeter, cgs unit of flux density, equivalent to lines per square inch in the English system, and webers per square meter or Tesla in the SI system.
Intrinsic Coercive force(Hcj)£¬Measured in Oersteds in the cgs system, this is a measure of the material's inherent ability to resist demagnetization. It is the demagnetization force corresponding to zero intrinsic induction in the magnetic material after saturation. Practical consequences of high Hci values are seen in greater temperature stability for a given class of material, and greater stability in dynamic operating conditions.
Isotropic magnet £¬A magnet material whose magnetic properties are the same in any direction.
Orientation Direction £¬The direction in which an anisotropic magnet should be magnetized in order to optimize the magnetic properties.
Oersted, Oe£ºA unit of magnetic field strength or magnetizing force.
Maximum Operating Temperature £¬ The maximum temperature of exposure that a magnet can forego without significant long-range instability or structural changes.
