Magnetizer's principle of work is: Imitates the first capacitor directs current the high-pressured voltage, then through a resistance minimum coil electric discharge. The discharge pulse electric current's peak value may amount to several thousand amperes. This current pulse produces a formidable magnetic field in the coil, this magnetic field causes to put in the coil the retentive material permanent magnetization. The magnetizer capacitor works when the pulse current peak value is extremely high, endures the surge current to the capacitor the performance requirement to be very high.

The magnetizer structure is simple, in fact is a magnetic force greatly strengthened electro-magnet, provides many kinds of shapes the iron slabs, takes the additional magnetic pole, in order to with is magnetized the build to become the closed magnetic circuit, when magnetizes, decorates the good additional magnetic pole, with is magnetized the body, so long as adds on the excitation circuit, brushes instantaneous then comple.
