How to measure the magnetic level? There are three main parameters: remanence Br ( 剩余 感应) Gauss, units, and removed from saturated magnetic field, after the rest of the magnetic flux density, on behalf of the foreign can provide the magnet magnetic field strength; Coercive force Hc ( 强制 力) Oersteds, unit, is to put the magnets in a reverse adscititious magnetic field, when applied magnetic field increases to a certain intensity magnet magnetic disappears, the resistance and the ability of the magnetic field is called the coercive force, represents a measure of resistance to demagnetization ability; Gauss - magnetic energy product BHmax, units 奥斯特, Is material produced by the magnetic energy per unit volume, how much is the magnet can store energy of a physical quantity.
