Cov hlau nplaum tas mus li yuav yog magnetizing ua ntej siv rau lawv qhov kev thov rau feem ntau. Cov hlau nplaum tas mus li yuav raug hlau nplaum thaum siv cov hlau nplaum los ntawm nws cov kev taw qhia thiab tom qab ntawd ua tiav cov txheej txheem saturation nrog lub zog sab nraud magnetic teb. Cov khoom sib txawv ntawm cov khoom sib nqus mus tas li xav tau cov khoom sib nqus sib txawv kom ua tiav cov txheej txheem saturation. Remanence Br thiab intrinsic coercivity Hcj yuav tsawg dua nws qhov tseem ceeb thaum sab nraud magnetic teb lub zog tsis tuaj yeem ncav cuag qhov kev sib nqus magnetic teb.
Yuav Ua Li Cas Magnetize Permanent Magnet?
Cov hlau nplaum tas mus li tuaj yeem sib nqus los ntawm ob qho tib si ncaj qha tam sim no magnetization thiab impulse magnetization. Direct tam sim no muaj xws li ncaj qha tam sim no lub hwj chim thiab electromagnet los yog magnetizing yoke. Direct tam sim no magnetic teb yuav tsim ib zaug ncaj qha tam sim no nkag mus rau hauv lub kauj. Sib nqus teb zog ntawm ob tug ncej ntawm lub electromagnet yog proportional rau lub kauj lemNthiab kev siv zog tam sim noI, 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 capacitor instantaneous tawm mus rau magnetizing kauj. Magnetizing coil yuav tsim cov magnetic teb nyob rau hauv lub sij hawm tam sim no muaj zog tam sim no los ntawm nws. Yog li ntawd, cov hlau nplaum ruaj khov nyob rau hauv coil yuav magnetized.
