1. N ncej, S ncej them thiab thim rov qab
Qhov xwm txheej no feem ntau tshwm sim nrog qee cov hlau nplaum tshwj xeeb, xws li cov hlau nplaum sib npaug nrog cov kaum sab xis. Qee cov neeg siv khoom xav kom qhov chaw nrog lub kaum sab xis txiav rau sab laug sab sauv yog S ncej. Qhov tshwm sim ntawm cov hlau nplaum tsis raug rau cov hlau nplaum no yuav ntau dua.
2. Txoj kev magnetization yuam kev (kev taw qhia)
Qhov no yuav yog vim kev sib txuas lus tsis zoo nrog tus neeg siv khoom. Piv txwv li, Xiao Fu muaj ib tug npoj yaig them D3.5 * 20 cylindrical hlau nplaum nrog radial magnetization. Tus neeg muas zaub Ameslikas thov axial magnetization. Hom no kuj yog ib qho tshwj xeeb heev, tab sis vim kuv tseem tsis tau lees paub nws, kuv tsuas yog txiav txim siab rau kuv tus kheej, uas ua rau muaj qhov yuam kev magnetization. Kuj tseem muaj cov hlau nplaum square uas muaj qhov yuam kev ntawm magnetization, txawm tias lawv yog thickness magnetization lossis sab magnetization. Cov pobzeb-hom hlau nplaum ntawm lub cev muaj zog uas yuav tsum muaj kev sib nqus sib nqus tsis sib haum rau kev sib nqus, thiab lwm yam. 3. Magnetization tsis saturated
Qhov xwm txheej no tsis tshua muaj, tab sis yuav muaj xwm txheej. Piv txwv li, lub tog raj kheej hlau nplaum tsuas tuaj yeem them nrog 20 cov hlau nplaum ncig ib zaug. Yog tias ntau tshaj 20 daim ntawm cov hlau nplaum ncig raug them, cov hlau nplaum ntawm nws yuav ua tsis tiav. Tau kawg, kuj muaj cov tshuab magnetic. Qhov teeb meem.
4. Cov hlau nplaum muaj cov khoom sib nqus tsis sib xws
Cov hlau nplaum yuav raug cuam tshuam los ntawm qhov sib nqus sib nqus tsis sib luag thaum lub sijhawm sib nqus hlau nplaum, ua rau cov hlau nplaum tsis sib xws. Qhov no yuav ua rau cov hlau nplaum tsim cov hlau nplaum tsis sib xws thaum siv, cuam tshuam rau nws cov kev ua tau zoo thiab cov nyhuv.
