Imagnethi
August 08, 2024
Iimagnethi zisetyenziswe ngabantu kangangeenkulungwane, kwaye iipropathi zabo ezingaqondakaliyo nezinamandla ziqhubeka zinomdla wenzululwazi kunye nabaphandi unanamhla. Ukusuka kwi-Granti Cerigerator yefriji ye-Magneting Presnance Reming (MRI) yoomatshini, iimagnethi zidlala indima ebalulekileyo kubomi bethu bemihla ngemihla nakwimizi-mveliso eyahlukeneyo. Ke, yintoni kanye kanye imagnethi kwaye basebenza njani?
Iimagnethi zizinto ezivelisa i-magnetic fildic, enamandla atsala okanye ipetshise izixhobo ezithile, ezinje ngentsimbi okanye intsimbi. Le ntsimi ye-magnetic yenziwa ngolungelelwaniso lweatom kwimagnethi, ebangela i-elektroni kwi-atom ukuba ijikeleze kwicala elinye. Olu nxibelelaniso ludala i-North kunye ne-South Pole ngaphakathi kwemagnethi, kunye ne-magnetic firling ukusuka kwi-North Pole ukuya kwiPole yaseMazantsi.
Zimbini iintlobo eziphambili zeMagnets: Iimagnethi ezisisigxina kunye nee-elektromagnets. Imagnethi esisigxina, efana nezo zifunyenwe kwi-Magnet yefriji, zigcine iipropathi zabo zemagneti ngaphandle kwesidingo sembali yangaphandle. Ezi zixhobo zihlala zenziwa zizixhobo ezinje ngentsimbi, i-nickel, kunye ne-cobabat, kwaye inokufumaneka kwimilo eyahlukeneyo kunye nobukhulu. I-Electromagnets, kwelinye icala, ziyimagnethi ezifuna umbane zangoku ukuze zivelise imagnethi. Ezi zixhobo zihlala zisetyenziswa kwizixhobo ezinjengeemotor zombane, abavelisi, kunye noomatshini be-MRI. Ngokudlula kombane ngokusebenzisa i-cire ye-wire irhangqiwe i-manytic core, i-electromagnet inokwenziwa. Amandla entsimi ye-magnetic eveliswe yi-electromagnet anokulawulwa ngokuhlengahlengisa inani lokuhamba kwe-wire.
Iimagnethi zinoluhlu olubanzi lwezicelo kumashishini ahlukeneyo. Kwicandelo lezempilo, iimagnethi zisetyenziswa kwiingoma ze-MRI ukwenza imifanekiso eneenkcukacha zamalungu angaphakathi omzimba kunye nezicubu. Kumzi-mveliso weemoto, iimagnethi zisetyenziswa kwizithuthi zombane ukuba zinamandla kwimoto kwaye zivelise intshukumo. Kwicandelo lezemveliso, iimagnethi zisetyenziswa kwiibhanti zokuhambisa ukuze zihlelele kwaye zahlukanise nezinto ezikwizinto zazo zemagneti. Imagnethi ikwadlala indima ebalulekileyo kwizixhobo zemihla ngemihla kunye negajethi. Ukusuka kwi-smartphones kunye neelaptops ukuya kutsho kunye nee-headsets, iimagnethi zisetyenziswa kwizixhobo ezahlukeneyo ze-elektroniki ukwenza isandi, idatha yevenkile, kunye nokubonelela ukusebenza. Ukongeza, iimagnethi zikwasetyenziswa kwizixhobo zasekhaya ezinjengeefriji, oomatshini bokuhlamba, kunye nee-microwave.
Ngaphandle kokusetyenziswa kwabo kwaye kubaluleke kakhulu, iimagnethi zisesifundo esiqhubekayo kunye nokuhlola. Izazinzulu zihlala zifunda iipropathi zemagazini kunye nokuphuhlisa izixhobo ezitsha kunye neetekhnoloji zokusebenzisa amandla abo ngokufanelekileyo. Ukusuka ekuphuculeni ukusebenza kwemali yombane ekuphuhliseni izixhobo zemagnethi ezitsha kwizicelo eziphambili, amathuba aneziganga azinasiphelo.
Ukuqukumbela, iimagnethi zinomdla kwizinto ezibe yinxalenye yempucuko yomntu kangangeenkulungwane. Iipropathi zabo ezahlukileyo kunye namabala amalunga namandla anamandla ezenza ukuba babe nakho kumashishini ahlukeneyo kunye nezixhobo zemihla ngemihla. Njengoko itekhnoloji iyaqhubeka ukuqhubela phambili, indima yeemagnethi ziya kuba lubaluleke ngakumbi ekubumbeni ikamva lokuzila kwekamva lokuphumeza nokufunyanwa.
