Gulu la maginito

Zida za ferromagnetic monga chitsulo, cobalt, nickel kapena ferrite ndizosiyana chifukwa ma electron spins amkati amatha kukonzedwa mwachisawawa pang'onopang'ono kuti apange dera lodzidzimutsa la magnetization, lomwe limatchedwa domain. Maginito a zida za ferromagnetic, maginito amkati mwadongosolo, njira yolowera mzere womwewo, kuti mphamvu ya maginito ipange maginito.
Mitundu yonse yazinthu zokhazikika zamaginito, monga aluminium faifi tambala ndi cobalt, samarium cobalt, ndfeb, izi ndizofala, maginito ndi amphamvu kwambiri, zinthu izi zitha kukhala maginito a maginito okhazikika maginito, ndipo pambuyo pa magnetization palokha imakhala ndi maginito. ndipo musasowe. The zikuchokera maginito yokumba zimadalira maginito ntchito zitsulo zosiyanasiyana ndipo anatsimikiza malinga ndi kufunika. Maginito ali pafupi ndi (kukhudza) chinthu cha maginito chomwe chimapangidwira kumtengo wina pafupi ndi mapeto ena ndi mtengo wa dzina lomwelo kumapeto kwake.

A. Maginito osakhalitsa (ofewa);
Tanthauzo: maginito ndi osakhalitsa ndipo amatha pamene maginito amachotsedwa. Chitsanzo: misomali, chitsulo.
B. Maginito okhazikika (olimba);
Kufunika: pambuyo maginito, maginito akhoza kusungidwa kwa nthawi yaitali. Chitsanzo: Msomali wachitsulo.

Pali magulu ambiri a maginito, ndingonena apa:
Pali magulu awiri akuluakulu a maginito:
Yoyamba ndi maginito okhazikika (omwe amadziwikanso kuti maginito olimba) : zinthuzo zimakhala ndi makhalidwe oteteza maginito.
Yachiwiri ndi magnetism yofewa (imatchedwanso electromagnet) : kufunikira kwakunja kwa magetsi kumatulutsa mphamvu ya maginito, timakhala athyathyathya ndi maginito omwe amati, ndikuloza kuzinthu za maginito okhazikika.
Palinso magulu awiri a maginito okhazikika:
Gulu loyamba ndi: aloyi okhazikika maginito zipangizo kuphatikizapo osowa lapansi okhazikika maginito zipangizo (ndfeb Nd2Fe14B), SmCo (samarium cobalt), NdNiCO (neodymium faifi tambala cobalt).
Gulu lachiwiri ndi Ferrite okhazikika maginito zipangizo, amene amagawidwa mu Sintered Ferrite, womangidwa Ferrite Magnet ndi jekeseni Ferrite malinga ndi njira zosiyanasiyana kupanga. Njira zitatuzi zimagawidwa kukhala maginito a isotropic ndi heterotropic malinga ndi momwe maginito amagwirira ntchito.
