MAGNITNOKI

MAGNITNOKI, tavsifi holati magnitii jismi fizikii makroskopi: hangomi qismi yakjinsa magnitnokshuda Magnitnoki chun momenti magnitii vohidi hajmi jism muayyan karda meshavad: / = —, in 40 M — momenti magnitii jism, v — hajmi on. Hangomi jismi gayriyakjinsa magnitnokshuda Magnitnoki baroi har yak nuqtai jism (aniktarash, baroi har yak hajmi khurdi fiziki dv) alohida muayyan karda meshavad: / , dar in jo dM — momenti magnitii hajmi dv. Vohidi Magnitnoki dar sistemai vohidhoi baynalkhalqi amper bar metr (1 —magnitnokiest, ki hangomi on 1 m3 modda doroi 1 Am2 momenti magnitist) meboshad. Magnitnoki ba maydoni magnitii beruna va harorat vobasta ast. (Nig. Paramagnetizm, Ferromagnetizm). Dar ferromagnetikii vobastagii ba shiddatnokii maydoni magnitii beruna N bo khati kaji maglitnokshavi ifoda meshavad (nig. Gisterezis). Dar moddahoi izotropi samti I bo samti N yakkhela va dar moddahoi anizotropi samthoi / va I dar mavridi umumi gunogunand.
