Kodi maginito amagwira ntchito bwanji?
kapangidwe ka atomiki | |
| Momwe maginito amagwirira ntchito zimatsimikiziridwa ndi kapangidwe kake ka atomiki. Atomu iliyonse imapangidwa ndi ma elekitironi olakwika omwe amazungulira ma protoni abwino ndi ma neutroni (otchedwa nucleus), omwe kwenikweni ndi maginito ang'onoang'ono okhala ndi ma poleni kumpoto ndi kummwera. |
 | Ma electron a maginito amayenda mozungulira mapulotoni, kupanga orbital magnetic field. Maginito ali ndi otchedwa theka chipolopolo cha ma elekitironi; mwa kuyankhula kwina, iwo sanaphatikizidwe ngati zipangizo zina. Kenako ma elekitironi amalumikizana, zomwe zimapanga mphamvu ya maginito. |
 | Ma atomu onse amaphatikizana kukhala magulu otchedwa makhiristo. Makristalo a ferromagnetic ndiye amadziyendetsa okha kumitengo yawo ya maginito. Kumbali ina, muzinthu zopanda ferromagnetic amakonzedwa mwachisawawa kuti athetse mphamvu iliyonse yamaginito yomwe angakhale nayo. |
 | Seti ya makhiristo kenako imalumikizana m'magawo, omwe pambuyo pake adzalumikizidwa munjira yomweyo ya maginito. Madomeni akamalozera mbali imodzi, mphamvu ya maginito imachulukira. |
 | Chinthu cha ferromagnetic chikakumana ndi maginito, madera omwe ali muzinthuzo amagwirizana ndi maginito. Zida zopanda ferromagnetic sizigwirizana ndi maginito ndipo zimakhalabe mwachisawawa. |
Kukopa kwa zinthu za ferromagnetic | |
 | Chinthu cha ferromagnetic chikalumikizidwa ku maginito, dera lotsekedwa limapangidwa chifukwa cha mphamvu ya maginito yomwe imachokera kumtunda wakumpoto kudzera pazitsulo za ferromagnetic kenako kumwera. |
 | Kukopa kwa chinthu cha ferromagnetic ku maginito komanso kuthekera kwake kuchigwira kumatchedwa mphamvu ya kukopa kwa maginito. Mphamvu yokoka ya maginito ikakoka, m'pamenenso imatha kukopa zinthu zambiri. |
 | Mphamvu ya kukopa kwa maginito imatsimikiziridwa ndi zinthu zingapo:
