Qhov sib txawv ntawm cov khoom sib nqus mos thiab cov khoom sib nqus tawv
1. Cov khoom sib nqus mos: siab permeability, yooj yim magnetization thiab demagnetization (loj pib susceptibility). Lub saturation magnetic induction muaj zog, coercivity (Hc) yog me me, thaj tsam ntawm hysteresis voj yog nqaim thiab ntev, thiab qhov poob yog me me (HdB cheeb tsam yog me me). Nws suav nrog cov hlau nplaum ntshiab, silicon steel permalloy (Fe, Ni) ferrite, thiab lwm yam. Nws yog tsim rau relay, lub cev muaj zog, sib nqus core thiab magnetic pas nrig ntawm ntau yam high-frequency electromagnetic Cheebtsam.
2. Hard magnetic materials: large coercive force (Hc) (>102A / m), loj remanence Br, loj cheeb tsam ntawm hysteresis voj, thiab loj poob. Xws li tungsten steel, carbon steel, aluminium nickel cobalt alloy, thiab lwm yam Kev Siv: Lub voj hysteresis dav thiab tuaj yeem tswj tau cov hlau nplaum muaj zog rau lub sijhawm ntev tom qab magnetization. Nws yog qhov tsim nyog rau kev ua cov hlau nplaum ruaj khov nyob rau hauv magnetoelectric meters, earphones thiab mus tas li magnetic loudspeakers.
