1. Kev xaiv tus neeg muag khoom
Xaiv cov khoom lag luam nrog cov khoom lag luam paub tab, kev paub nplua nuj, thiab cov txheej txheem tsim khoom nruj. Cov neeg muag khoom no tuaj yeem muab cov hlau nplaum zoo - zoo, txhim khu kev qha, thiab ntev - cov hlau nplaum ntev ntev.
2. Magnet Parameter Kev txiav txim siab
Thaum xaiv cov hlau nplaum nkhaus, ua tib zoo saib rau cov hauv qab no:
(1) Magnetic Properties: Cov khoom sib nqus ntawm cov hlau nplaum nkhaus yog qhov tseem ceeb.
(2) Saturation Magnetic Field: Lub saturation magnetic teb yog hais txog qhov siab tshaj plaws magnetic teb uas cov hlau nplaum nkhaus tuaj yeem muab tau.
(3) Kev Ua Haujlwm Kub: Qhov kev ua haujlwm kub yog hais txog qhov kub siab tshaj plaws uas siv cov hlau nplaum nkhaus.
3. Cov xwm txheej siv tau
Xaiv cov hlau nplaum nkhaus nrog cov yam ntxwv sib txawv raws li cov kev xav tau tshwj xeeb kom ua tau raws li cov ntawv thov scenarios.
