Yuav Ua Li Cas Magnetize Permanent Magnet?
Cov hlau nplaum ruaj khov tuaj yeem sib nqus los ntawm ob qho tib si ncaj qha tam sim no magnetization thiab impulse magnetization. Lub kaw lus ncaj qha tam sim no suav nrog lub zog ncaj qha tam sim no thiab electromagnet lossis hlau nplaum sib nqus. Qhov ncaj qha tam sim no magnetic teb yuav tsim ib zaug cov tam sim no ncaj qha nkag mus rau hauv lub kauj. Sib nqus lub zog ntawm ob tug ncej ntawm electromagnet yog proportional rau lub kauj tig N thiab tam sim no siv I, thiab inversely proportional rau qhov sib txawv ntawm ob tug ncej ntawm electromagnet. Ob leeg electromagnet thiab magnetizing yoke yog qhov nyuaj heev rau magnetize high-coercivity mus tas li hlau nplaum rau kev saturation. Rau impulse magnetization, lub capacitor yuav raug them tom qab rectification, ces lub zog hluav taws xob nyob rau hauv lub capacitor instantaneous tawm mus rau lub magnetizing kauj. Lub magnetizing coil yuav tsim cov pulsed magnetic teb thaum lub sij hawm muaj zog instantaneous tam sim no los ntawm nws. Yog li ntawd, cov hlau nplaum ruaj khov nyob rau hauv lub kauj yuav magnetized.
