Kodi maginito ali ndi mphamvu yotani yokoka?Anthu ena amaganiza kuti maginito a NdFeB amatha kukoka zinthu ndi nthawi 600 monga kulemera kwake.Kodi izi ndendende?Kodi pali njira yowerengera yoyamwa maginito?Lero, tiyeni tikambirane za "Kukoka Mphamvu" ya maginito.
Pogwiritsa ntchito maginito, kusinthasintha kwa maginito kapena kachulukidwe ka maginito ndikofunikira kwambiri kuti muyeze magwiridwe antchito (makamaka ma motors).Komabe, m'malo ena ogwiritsira ntchito, monga kupatukana kwa maginito ndi kusodza kwa maginito, kusinthasintha kwa maginito si njira yabwino yolekanitsira kapena kuyamwa, ndipo mphamvu yokoka ya maginito ndiyomwe imagwira ntchito kwambiri.
Mphamvu yokoka ya maginito imatanthawuza kulemera kwa zinthu za ferromagnetic zomwe zimatha kukopeka ndi maginito.Zimakhudzidwa limodzi ndi momwe maginito amagwirira ntchito, mawonekedwe, kukula ndi mtunda wokopa.Palibe chilinganizo cha masamu chowerengera kukopa kwa maginito, koma titha kuyeza kuchuluka kwa maginito kukopa kudzera mu chipangizo choyezera chokopa (nthawi zambiri kuyeza kuthamanga kwa maginito ndikusinthira kulemera kwake), monga momwe tawonera pachithunzichi.Mphamvu yokoka ya maginito idzachepa pang'onopang'ono ndi kuwonjezeka kwa mtunda wa chinthu chokopa.
Ngati inu kufufuza maginito mphamvu mawerengedwe pa Google, Websites ambiri adzalemba "malinga ndi zinachitikira, ndi maginito mphamvu NdFeB maginito ndi za 600 nthawi kulemera kwake (640 zina olembedwanso)".Kaya chochitikachi ndi cholondola kapena ayi, tidzadziwa kudzera muzoyesera.
Maginito a Sintered NdFeB n42 okhala ndi mawonekedwe ndi makulidwe osiyanasiyana adasankhidwa pakuyesa.Chophimba pamwamba chinali NiCuNi, chomwe chinapangidwa ndi maginito kudzera mumayendedwe aatali.Mphamvu yayikulu kwambiri (N pole) ya maginito aliwonse idayezedwa ndikusinthidwa kukhala kulemera kokopa.Zotsatira zake ndi izi:
Sizovuta kupeza kuchokera pazotsatira zoyezera:
- Chiyerekezo cha kulemera komwe maginito amitundu yosiyanasiyana ndi makulidwe amatha kukopa kulemera kwawo kumasiyana kwambiri.Zina ndi zosakwana nthawi 200, zina kuposa nthawi 500, ndipo zina zimatha kufika maulendo oposa 3000.Chifukwa chake, nthawi 600 zolembedwa pa intaneti sizolondola kwathunthu
- Kwa Cylinder kapena Disc Magnet yokhala ndi m'mimba mwake womwewo, kutalika kwake, kumapangitsanso kulemera komwe kumatha kukopa, ndipo mphamvu yamaginito imakhala yolingana ndi kutalika kwake.
- Kwa Magnet ya Cylinder kapena Disc yautali womwewo (maselo abuluu), kukula kwake, kulemera kwake komwe kumatha kukopa, ndipo mphamvu ya maginito imakhala yolingana ndi m'mimba mwake.
- M'mimba mwake ndi kutalika kwa Cylinder kapena Disc Magnet (selo lachikasu) lokhala ndi voliyumu ndi kulemera kwake ndizosiyana, ndipo kulemera komwe kumatha kukopeka kumasiyana kwambiri.Nthawi zambiri, ngati maginito akupita kwanthawi yayitali, imakoka kwambiri
- Kwa maginito okhala ndi voliyumu yofanana, mphamvu yamaginito sikhala yofanana.Malinga ndi maonekedwe osiyanasiyana, mphamvu ya maginito imatha kusiyana kwambiri.Momwemonso, maginito omwe amakopa kulemera kofanana kwa zida za ferromagnetic amatha kukhala ndi mawonekedwe osiyanasiyana, ma voliyumu ndi zolemera.
- Ziribe kanthu kuti ndi mawonekedwe anji, kutalika kwa mbali yolowera kumatenga gawo lalikulu pakuzindikira mphamvu ya maginito.
Pamwambapa ndi kuyesa mphamvu yokoka kwa maginito a giredi lomwelo.Nanga bwanji mphamvu yokoka ya maginito osiyanasiyana amagulu osiyanasiyana?Tidzayesa ndikufanizira pambuyo pake.
