Kuyeza Makhalidwe Okhazikika a Maginito

Kuyesa Magineti Kosatha: Maganizo a Katswiri

Kufunika kwa Kuyeza Molondola
Ngati mumagwira ntchito ndi zinthu zamaginito, mukudziwa kuti magwiridwe antchito odalirika amayamba ndi muyeso wolondola. Deta yomwe timasonkhanitsa kuchokera ku mayeso a maginito imakhudza mwachindunji zisankho mu uinjiniya wamagalimoto, zamagetsi zamagetsi, ukadaulo wazachipatala, ndi kugwiritsa ntchito mphamvu zongowonjezwdwanso.

Magawo Anayi Ofunikira Ogwira Ntchito
Tikamayesa maginito okhazikika mu labu, nthawi zambiri timayang'ana magawo anayi ofunikira omwe amafotokoza luso lawo:

Br: Chikumbutso cha Magnet
Kubwerera m'mbuyo (Br):Taganizirani izi ngati "chikumbutso" cha maginito cha maginito. Tikachotsa gawo lakunja la maginito, Br imatiwonetsa kuchuluka kwa mphamvu ya maginito yomwe zinthuzo zimasunga. Izi zimatipatsa maziko a mphamvu ya maginito yomwe imagwiritsidwa ntchito.

Hc: Kukana Kuchepetsa Mphamvu ya Magetsi
Kukakamiza (Hc):Taganizirani izi ngati "mphamvu" ya maginito - kuthekera kwake kukana kuchotsedwa kwa maginito. Tikugawa izi kukhala Hcb, yomwe imatiuza gawo lobwerera lomwe likufunika kuti tichotse mphamvu ya maginito, ndi Hci, yomwe imatiwonetsa kuchuluka kwa mphamvu yomwe tikufunika kuti tichotse kwathunthu kukhazikika kwa maginito.

BHmax: Chizindikiro cha Mphamvu
Mphamvu Yochuluka Kwambiri (BHmax):Iyi ndi nambala yodzaza ndi mphamvu yomwe timakoka kuchokera mu hysteresis loop. Imayimira kuchuluka kwa mphamvu komwe maginito angapereke, zomwe zimapangitsa kuti ikhale njira yathu yodziwira mitundu yosiyanasiyana ya maginito ndi magwiridwe antchito.

Hci: Kukhazikika Pansi pa Kupanikizika
Kukakamiza Kwamkati (Hci):Pa maginito a NdFeB omwe amagwira ntchito bwino masiku ano, iyi ndiye mfundo yoti igwiritsidwe ntchito. Pamene ma Hci ali amphamvu, maginito amatha kupirira nyengo zovuta - kuphatikizapo kutentha kwambiri komanso mphamvu zamaginito zomwe zimalimbana ndi magetsi - popanda kutayika kwakukulu kwa magwiridwe antchito.

Zida Zofunikira Zoyezera
M'machitidwe athu, timadalira zida zapadera kuti tigwire ntchito imeneyi. Hysteresisgraph ikupitilizabe kukhala njira yathu yogwirira ntchito m'ma laboratories, ikujambula BH curve yonse kudzera mu maginito olamulidwa. Pa fakitale, nthawi zambiri timasinthira ku mayankho onyamulika monga Hall-effect gaussmeters kapena Helmholtz coils kuti titsimikizire bwino khalidwe mwachangu.

Kuyesa Maginito Okhala ndi Zomatira
Zinthu zimakhala zovuta kwambiri tikamayesamaginito a neodymium okhala ndi guluuKusavuta kwa guluu womangidwa mkati kumabwera ndi zovuta zina zoyesera:

Mavuto a Masewera
Mavuto Okwera:Chigawo chomata chimenecho chimatanthauza kuti maginito samakhala bwino kwambiri mu zida zoyesera zokhazikika. Ngakhale mipata ya mpweya wochepa kwambiri ingasokoneze kuwerenga kwathu, zomwe zimafuna njira zatsopano zoyikira bwino.

Zoganizira za Jiyomethri
Zoganizira za Fomu:Kapangidwe kawo kopyapyala komanso kopindika kamafuna kukonzedwa mwamakonda. Makonzedwe wamba opangidwira mabuloko olimba sagwira ntchito ngati chitsanzo chanu choyesera chingasunthe kapena sichikhala ndi makulidwe ofanana.

Zofunikira pa Malo Oyesera
Zofunikira pa Kudzipatula kwa Maginito:Monga mayeso onse a maginito, tiyenera kukhala odzipereka kwambiri pa kusunga chilichonse chosakhala ndi maginito pafupi. Ngakhale kuti guluu palokha silili ndi maginito, zida zilizonse zachitsulo kapena maginito ena omwe ali pafupi angawononge zotsatira zathu.

Chifukwa Chake Kuyesa Kuli Kofunika？
Kuyesa kolondola n'kofunika kwambiri. Kaya ndife maginito oyenerera magalimoto amagetsi kapena zida zoyezera matenda, palibe cholakwika. Ndi mitundu yomatira, sitikungoyang'ana mphamvu ya maginito - tikutsimikiziranso kulimba kwa kutentha, chifukwa guluu nthawi zambiri limalephera maginito okha pakakhala kutentha kwambiri.

Maziko a Kudalirika
Pamapeto pake, kuyesa bwino maginito sikungoyang'ana khalidwe lokha - ndi maziko a magwiridwe antchito odziwikiratu pa ntchito iliyonse. Mfundo zazikulu zimakhala chimodzimodzi pa mitundu yonse ya maginito, koma akatswiri anzeru amadziwa nthawi yosinthira njira zawo pazinthu zapadera monga mapangidwe okhala ndi zomatira.
