1. Hom magnetization qauv
Orientation (Anisotropy): Zoo dua hlau nplaum nyob rau hauv ib qho kev taw qhia. Thaum lub sij hawm fabrication, ib tug magnetic teb yog siv raws li ib tug nyiam magnetization kev taw qhia rau oriented cov khoom thiab ua rau kom cov kev ua tau zoo ntawm cov hlau nplaum. Siv cov khoom siv taw qhia, cov hlau nplaum sib nqus sib nqus "dhau los ntawm" cov hlau nplaum, ua rau ob sab ntawm cov hlau nplaum muaj zog.
Non-directional (isotropic): muaj cov khoom sib nqus zoo ib yam hauv txhua qhov kev qhia. Thaum lub sijhawm tsim khoom, cov hlau nplaum tsis raug rau cov hlau nplaum. Cov khoom no tuaj yeem sib nqus hauv txhua hom kev sib nqus. Cov khoom siv no tsis muaj zog dua li cov khoom siv taw qhia. Rau cov ntaub ntawv uas tsis yog-oriented, multipolar magnetizing flux khoov rau hauv cov hlau nplaum kom nws muaj zog ntawm ib sab xwb.
2. Cov qauv hlau nplaum siv tau rau ob qho tib si taw qhia thiab tsis yog cov khoom siv hlau nplaum.
khiav dhau
Lub bar ntawm qhov ntev - ib kawg yog magnetized North thiab lwm kawg yog magnetized South.
rod
Hla qhov ntev lossis axis - magnetize North ntawm ib kawg thiab Sab Qab Teb ntawm lwm qhov.
thaiv los ntawm thickness
- Magnetize North ntawm ib sab ntawm tuab thiab Sab Qab Teb ntawm lwm qhov.
ib tug disc los yog nplhaib los ntawm lub thickness
- Ib sab ntawm disc magnetizes North thiab lwm sab magnetizes South.
square hlau nplaum
Hla Dav lossis Hla Dav - Magnetize North ntawm ib sab ntawm qhov dav thiab Sab Qab Teb rau lwm qhov.
puag ncig
Ntau tus ncej (ob lossis ntau dua) ntawm qhov chaw Magnetized los ntawm cov tuab - Magnetized nrog ntau tshaj ib txheej ntawm N / S ncej ntawm ib lossis ob lub ntsej muag ntawm cov hlau nplaum.
3. Saj zawg zog sib nqus ncej qauv
A. Pa magnetization: Muaj ib tug ncej ntawm txhua sab ntawm cov hlau nplaum. Ib sab yog North Ncej thiab lwm sab yog South Ncej.
B. Multipole (Standard): Ob tug ncej ntawm ib sab (B1) lossis ntau tus ncej (B2); ob lossis ntau pawg ntawm cov ncej ntawm txhua lub ntsej muag rau kev tsim qauv qhib. Sab qaum teb thiab sab qab teb ncej hloov los ntawm cov thickness ntawm cov khoom. Thaum ua tau zoo, steel thaub qab yog qhov zoo dua.
