Rarraba Magnets

Kayayyakin ferromagnetic kamar baƙin ƙarfe, cobalt, nickel ko ferrite sun bambanta ta yadda za a iya shirya jujjuyawar wutar lantarki ta ciki ba tare da bata lokaci ba a cikin ƙaramin kewayo don samar da yankin magnetization na kwatsam, wanda ake kira domain. Magnetization na ferromagnetic kayan, da ciki Magnetic yankin neatly, da shugabanci na daya line up, sabõda haka, da Magnetic ƙarfi, ya zama maganadisu.
Duk nau'ikan kayan maganadisu na dindindin, irin su aluminum nickel da cobalt, samarium cobalt, ndfeb, waɗannan suma na kowa ne, magnetic yana da ƙarfi sosai, waɗannan abubuwa na iya zama magnetization na filin maganadisu na filin maganadisu akai-akai, kuma bayan magnetization kanta yana da Magnetic. kuma kada ku bace. Abubuwan da ke tattare da maganadisun wucin gadi ya dogara da aikin magnetization na ƙarfe daban-daban kuma an ƙaddara bisa ga buƙata. Magnet yana kusa da (taɓawa) wani abu na maganadisu wanda aka jawo shi zuwa wani kishiyar sandar sanda kusa da ƙarshen ɗaya kuma zuwa sandar suna ɗaya a ɗayan ƙarshen.

A. Magnet na ɗan lokaci (mai laushi);
Muhimmanci: maganadisu na ɗan lokaci ne kuma yana ɓacewa lokacin da aka cire maganadisu. Misali: ƙusoshi, ƙarfe na ƙarfe.
B. Magnet na dindindin (mai wuya);
Mahimmanci: bayan magnetization, magnetism za a iya riƙe na dogon lokaci. Misali: ƙusa karfe.

Akwai nau'ikan maganadisu da yawa, kawai zan ce anan:
Akwai manyan nau'ikan kayan maganadisu guda biyu:
Na farko kayan maganadisu na dindindin (wanda kuma aka sani da Hard Magnetic): kayan da kansa yana da halaye na adana maganadisu.
Na biyu shi ne magnetism mai laushi (kuma ana kiransa electromagnet): buƙatar ƙarfin wutar lantarki na waje yana samar da ƙarfin maganadisu, muna da lebur shine magnet ɗin ya ce, yana nunawa ga kayan maganadisu na dindindin.
Hakanan akwai nau'ikan kayan maganadisu na dindindin:
Kashi na farko shine: kayan maganadisu na alloy na dindindin wanda ya haɗa da kayan Magnetic na dindindin na duniya (ndfeb Nd2Fe14B), SmCo (samarium cobalt), NdNiCO (neodymium nickel cobalt).
Kashi na biyu shine kayan maganadisu na dindindin na Ferrite, waɗanda aka raba su zuwa Sintered Ferrite, haɗin Ferrite Magnet da allura Ferrite bisa ga tsarin samarwa daban-daban. Wadannan matakai guda uku an raba su zuwa isotropic da heterotropic maganadiso bisa ga mabanbanta fuskantarwa na Magnetic lu'ulu'u.
