Demystifying Strong Magnets

Chii Chaizvo Chinopa Magnet Kushanda Kwayo Kwakasimba?

Kana nyanzvi dzehunyanzvi dzichitaura nezvemagineti se "yakasimba," haiwanzo kumiswa panhamba imwechete kubva pane imwe pepa. Simba remagineti rechokwadi rinobva mukudyidzana kwezvivakwa zvakawanda mumamiriro epasirese-uye uyu musanganiswa unopatsanura kuita kwedzidziso kubva pakubudirira kwaungavimba nazvo mukuita.

Zvinhu zvakati wandei zvakabatana zvinosarudza chaiyo magineti kuita:

Chekutanga iremanence (Br), iyo inoverengera iyo magineti flux inochengeta magineti kana yabviswa kubva mumunda wayo wemagnetizing. Funga nezvayo se "chigadziko chekunamira" chemagineti - kugona kwekutanga kunamatira kune ferromagnetic zvinhu kwenguva refu mushure mekutanga magineti yapera. Pasina remanence yakakwana, kunyangwe magineti akagadzirirwa simba anonetsa kuchengetedza kubata mukushandiswa kwezuva nezuva.

Chechipiri ndiko kumanikidza (Hc), chiyero chekuti magineti anorambisisa sei demagnetization kubva kumanikidziro ekunze. Aya madzvinyiriro anogona kubva pakurovera magineti minda (yakajairwa mumaindasitiri ane maturusi akawanda) kuenda kune yakaramba ichipisa yekushushikana (semuinjini bays kana welding nzvimbo). Mukushandisa uko kukundikana kunogona kukanganisa mashandiro - semidziyo yekufungidzira yekurapa kana magadzirirwo ekugadzira - kumanikidza kwakanyanya haisi bhonasi chete; chinhu chisingataurwi chinodiwa kuti uve nechokwadi chekushanda kunoenderana.

Yetatu kumusoro ndiyo yakanyanya simba chigadzirwa (BHmax), metric inotsanangudza simba remagineti: kuisa zviri nyore, inoyera kuti ingani simba remagineti rinogona kuiswa mukati mehukuru hwemagineti. Huwandu hwepamusoro hweBHmax hunoreva kuburitsa simba rakawanda rekudhonza kubva kune magineti idiki uye yakareruka-uye iyi ishanduko yemitambo yemagadzirirwo apo nzvimbo iri pamutengo wepamusoro, senge compact yemagetsi zvishandiso kana zvikamu zvemotokari. Ichi chiyero chinobatana zvakananga kune chaiyo-yepasirese kushanda zvakanaka, zvakare: magineti ine yakasimba BHmax inoita kuti mainjiniya agadzire zvigadzirwa zvakapfava, zvakakwenenzverwa pasina kusiya simba rinodiwa kuti basa riitwe. Izvi zvinhu zvitatu pamwe chete zvinoumba musana wekuita kwemagneti mukushandisa kunoshanda-hapana inoshanda yega, uye chiyero chiri pakati pazvo ndicho chinosarudza kana magineti ichaita zvakanaka mubasa rayo rainoda kana kutadza kusangana nemucherechedzo.

Kana iwe ukarongedza ese magineti anogara aripo nhasi, neodymium mhando dzinogara dzichibuda pamberi pechinyakare sarudzo senge ferrite uye alnico pane ese aya zviyero.

Iyo Sainzi Kuseri kweNeodymium's Superiority?

Kubva zvakarova chiitiko mu1980s, neodymium magineti akachinja dhizaini mukana apo nzvimbo yakamanikana asi simba remagineti harigone kukanganisika. Kugona kwavo kwakasiyana kunobva mukati mukati meatomu yavo yekuvaka:

Iyo yakasarudzika tetragonal crystal kurongeka muNdFeB inogadzira izvo zvinhu masayendisiti anodaidza magnetocrystalline anisotropy. Mune mazwi anoshanda, izvi zvinoreva kuti mukati magineti zvimiro zvakarongeka zvakarongeka nenzira inodiwa, zvichigadzira kusimba kwemunda kunoshamisa.

Aya magineti anounza zvese zvakakura remanence uye kucherechedzwa kumanikidza patafura, zvichivagonesa kuchengetedza yakasimba magineti minda vachimira kune demagnetization pressure. Uku kuita kwakadzikama kunoratidza kunonyanya kubatsira mukushandisa zvine simba uko mamiriro asingawanzo kugara akakwana.
