Ndi Zinthu Ziti Zabwino Kwambiri Zopangira Magnet Yokhazikika?

Maginito osathandizofunikira pamagwiritsidwe osiyanasiyana, kuyambira ma mota amagetsi kupita ku zida zosungira maginito. Kumvetsetsa zida zabwino kwambiri zopangira maginitowa ndikofunikira kuti muwongolere magwiridwe antchito awo komanso kuchita bwino.
Zida zodziwika bwino zopangira maginito okhazikika ndi neodymium, samarium-cobalt, ferrite, ndi alnico. Chilichonse mwazinthuzi chimakhala ndi zinthu zapadera zomwe zimawapangitsa kukhala oyenera ntchito zosiyanasiyana.

Maginito a Neodymium: Nthawi zambiri amatchedwa maginito a NdFeB, maginito a neodymium amapangidwa kuchokera ku aloyi ya neodymium, chitsulo, ndi boron. Amadziwika ndi mphamvu zawo zapadera za maginito, zomwe zimawapangitsa kukhala maginito amphamvu kwambiri omwe amapezeka. Zopangira zawo zamphamvu zamaginito zimapangitsa kuti pakhale mapangidwe ang'onoang'ono komanso opepuka pamapulogalamu monga ma mota ndi ma jenereta. Komabe, amatha kukhala ndi dzimbiri, kotero kuti zokutira zoteteza nthawi zambiri zimakhala zofunikira.

Maginito a Samarium-Cobalt: Maginitowa amapangidwa kuchokera ku kuphatikiza samarium ndi cobalt. Amadziwika ndi kukana kwawo kwa demagnetization komanso kukhazikika kwabwino kwamafuta, kuwapangitsa kukhala abwino pakugwiritsa ntchito kutentha kwambiri. Ngakhale ndi okwera mtengo kwambiri kuposa maginito a neodymium, kulimba kwawo komanso magwiridwe antchito ake pamikhalidwe yovuta kwambiri kumawapangitsa kukhala okonda kwambiri muzamlengalenga ndi ntchito zankhondo.

Maginito a Ferrite: Wopangidwa ndi chitsulo okusayidi ndi zinthu zina zachitsulo, maginito a ferrite ndi otsika mtengo komanso amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zogula. Ndiwochepa mphamvu kuposa maginito a neodymium ndi samarium-cobalt koma amalimbana kwambiri ndi dzimbiri ndipo amatha kugwira ntchito pakatentha kwambiri. Kutsika kwawo kumawapangitsa kukhala chisankho chodziwika bwino pamapulogalamu ngati maginito afiriji ndi zokuzira mawu.

Alnico Magnets: Opangidwa kuchokera ku aluminiyamu, faifi tambala, ndi cobalt, maginito a alnico amadziwika kuti amatha kupirira kutentha kwambiri komanso kukhazikika kwawo kwa maginito. Nthawi zambiri amagwiritsidwa ntchito pamapulogalamu omwe amafunikira mphamvu yamagetsi yokhazikika, monga magitala amagetsi ndi masensa.

Pomaliza, zinthu zabwino kwambiri zopangira maginito okhazikika zimatengera zofunikira pakugwiritsa ntchito. Maginito a Neodymium amapereka mphamvu zosayerekezeka, pamene samarium-cobalt amapereka kukhazikika kwa kutentha kwambiri. Maginito a Ferrite ndi alnico amagwira bwino ntchito zotsika mtengo, kuwonetsa mitundu yosiyanasiyana yazinthu zomwe zilipo popanga maginito okhazikika.
