(Demagnetization Curves yeN40UH Neodymium Magnet)
Magnets ave achifadza vanhu kwemazana emakore, achiratidza masimba anofadza anoita seasingatsananguriki.Pamwoyo wesimba remagineti pane demagnetization curve, pfungwa yakakosha mukunzwisisa magineti ayo.Mune ino blog positi, isu tinotanga rwendo rwekudzima demagnetization curve, kuburitsa zvakavanzika kuseri kwekuvakwa kwayo uye kukosha kwayo mukushandisa kwakasiyana.Saka, ngatinyure munyika yemagnetism uye tiongorore ichi chinonakidza chiitiko!
Demagnetization curve yakaziviswa
A demagnetization curve, inozivikanwawo semagineti curve kana hysteresis loop, inoratidza maitiro echinhu chemagnetic kana ichiiswa pasi pekuchinja kwemagineti.Inoratidza hukama pakati pesimba remagineti uye mhedzisiro yemagineti induction kana flux density.Nekuronga simba remagineti (H) pane x-axis uye magineti flux density (B) pane y-axis, demagnetization curves inotibvumira kunzwisisa uye kuongorora magineti emhando yezvinhu.
Kunzwisisa Maitiro eMagnetic Materials
Nekutarisa pa demagnetization curves, tinogona kuona akakosha ma paramita anotsanangura maitiro echinhu munzvimbo dzakasiyana dzemagineti.Ngationgororei zvinhu zvitatu zvakakosha:
1. Saturation point: Pakutanga, iyo curve inonyura zvakanyanya kusvika yasvika pachikumbaridzo, panguva iyo hapana kuwedzera kwesimba remagineti kuchakanganisa huwandu hwekuyerera.Pfungwa iyi inoratidza kuzara kwezvinhu.Zvishandiso zvakasiyana zvine mapoinzi akasiyana ekuzadza, ayo anomiririra kugona kwavo kuramba magineti pasi pesimba rakasimba remagineti.
2. Kumanikidza: Kuramba uchitevedza curve, simba remagineti rinoderera, zvichiita kuti kuderera kwemagnetic flux density.Nekudaro, kana izvo zvikaramba zvichichengeta imwe dhigirii remagnetization, pachave nenzvimbo iyo iyo curve inopindirana ne x-axis.Mharadzano iyi inomiririra simba rekumanikidza, kana simba rekumanikidza, rinoratidza kuramba kwechinhu ku demagnetization.Zvishandiso zvine high coercivity zvinoshandiswa mumagineti echigarire kana zvimwe zvisingaperi magineti application.
3. Remanence: Kana simba remagineti rasvika zero, curve inopindirana ney-axis kupa remanence flux density kana remanence.Iyi parameter inoratidza dhigirii iyo iyo chinhu chinoramba chiri magineti kunyangwe mushure mekubviswa kwemagineti ekunze.High remanence yakakosha kune zvikumbiro zvinoda kugara kwenguva refu magineti maitiro.
Kushandisa uye Kukosha
Demagnetization curves inopa nzwisiso yakakosha mukusarudza kwezvinhu uye optimization kune akasiyana siyana ekushandisa.Heino mimwe mienzaniso yakakosha:
1. Motors: Kuziva demagnetization curve kunobatsira mukugadzira mota dzinoshanda dzine optimized magineti zvinhu zvinokwanisa kumira magineti akakwirira pasina demagnetization.
2. Magnetic data kuchengetedza: Demagnetization curves inobatsira mainjiniya kukudziridza yakakwana magineti yekurekodha midhiya nekumanikidza kwakaringana kwekuvimbika uye kwakasimba kuchengetedza data.
3. Electromagnetic Devices: Kugadzira inductor cores uye matransformer kunoda kunyatsotariswa kwe demagnetization curves kuti ienderane nemagetsi uye ma mechanical zvinodiwa.
Mhedziso
Dzvanya munyika yemagineti kuburikidza nelenzi ye demagnetization curves, ichiratidza kuomarara kwemaitiro emagineti uye mashandisiro azvo.Nekushandisa simba reiyi curve, mainjiniya ari kugadzirira nzira yekufambira mberi kune akasiyana siyana minda, achigadzira mamiriro etekinoroji eramangwana.Saka nguva inotevera paunosangana nemagineti, tora kanguva kuti unzwisise sainzi kuseri kwemagineti yayo uye zvakavanzika zvakavigwa mune yakapusa demagnetization curve.
