UMagnets usetshenziswe ngabantu izinkulungwane zeminyaka, futhi izakhiwo zabo ezingaqondakali nezinamandla ziyaqhubeka ukuheha ososayensi nakubacwaningi kuze kube namuhla. Ukusuka kwisiqandisi esilula esiqandisiwe kumishini eyinkimbinkimbi yama-Magnetic Resonance imaging (MRI), ama-magnets adlala indima ebalulekile empilweni yethu yansuku zonke nasezimbonini ezahlukahlukene. Ngakho-ke, yini ngempela ama-marthets futhi asebenza kanjani?
Ama-Magnets yizinto ezikhiqiza amandla kazibuthe, okuwubutho obudonsela noma oxosha izinto ezithile, njengensimbi noma ngensimbi. Le nkambu kazibuthe idalwe ukuhambisana kwama-athomu ngaphakathi kwe-magnet, okubangela ama-elektroni kuma-athomu ukuba angene ngendlela efanayo. Lokhu kuqondanisa kwakha isigxobo saseNyakatho neSouth ngaphakathi kwe-Magnet, ngamandla kazibuthe ageleza evela eNorth Pole eSouth Pole.
Kunezinhlobo ezimbili eziphambili zikaMagnets: Ama-Magnets ahlala njalo kanye nama-elekthronikhi. Ama-Magnets angapheli, njengaleyo etholakala ku-Dengrinditor Magrets, gcina izakhiwo zawo zamandla kazibuthe ngaphandle kwesidingo sensimu yama-magnetic yangaphandle. Lezi zimantshi zivame ukwenziwa ngezinto zokwakha ezifana ne-iron, nickel, kanye ne-cobalt, futhi zitholakala ngezimo ezahlukahlukene nosayizi. Ama-elektromagnets, ngakolunye uhlangothi, ama-marthets adinga amanzi kagesi ukukhiqiza amandla kazibuthe. Lezi zibuthe zivame ukusetshenziswa kumadivayisi afana nama-motor kagesi, abakhiqizi kanye nemishini ye-MRI. Ngokudlula ngogesi wamanje ngokusebenzisa ikhoyili yocingo esongelwe umnyombo kazibuthe, ingakhiwa i-electromagnet. Amandla amandla kazibuthe akhiqizwa yi-electromagnet angalawulwa ngokulungisa inani lokugeleza kwamanje ngocingo.
Ama-Magnets anezicelo ezahlukahlukene ezimbonini ezahlukahlukene. Emkhakheni wezokunakekelwa kwempilo, kusetshenziswa ama-magnets emishini ye-MRI ukudala izithombe ezinemininingwane yezitho zangaphakathi zomzimba. Embonini yezimoto, ama-magnets asetshenziswa ezimotweni zikagesi ukukhulisa imoto futhi akhiqize ukunyakaza. Emkhakheni wezokukhiqiza, kusetshenziswa ama-magnets kumabhande okuhambisa ukuhlela nokuhlukanisa izinto ezisuselwa kwizakhiwo zazo zasolwandle. Ama-Magnets nawo adlala indima ebalulekile kumadivayisi wansuku zonke namagajethi. Kusuka kuma-Smartphones kanye nama-laptops kwizikhulumi namahedfoni, ama-magnets asetshenziswa emishini ye-elekthronikhi ehlukahlukene ukudala idatha yomsindo, yesitolo, futhi anikeze ukusebenza. Ngaphezu kwalokho, ama-magnets nawo asetshenziswa emishini yasendlini njengeziqandisini, imishini yokuwasha, kanye nama-oveno we-microwave.
Naphezu kokusebenzisa kwabo okusakazekile nokubaluleka, ama-magnets aseseyindaba yokucwaninga okuqhubekayo nokuhlola. Ososayensi bavame ukutadisha izakhiwo zikaMagnets futhi bakha izinto ezintsha nobuchwepheshe ukubopha amandla abo ngempumelelo. Ukusuka ekuthuthukiseni ukusebenza kahle kwama-motor kagesi ekwakheni izinto ezintsha zemagnethi ukuze kusetshenziswe izinhlelo ezithuthukile, amathuba anama-magnets awapheli.
Ekuphetheni, ama-magnets ayizinto ezihehayo eziye zaba yingxenye yempucuko yabantu amakhulu eminyaka. Izakhiwo zazo ezihlukile namasimu kazibuthe anamandla abenza babe nokubaluleka ezimbonini ezahlukahlukene namadivayisi wansuku zonke. Njengoba ubuchwepheshe buqhubeka buqhubekisela phambili, iqhaza lama-magnets lizobe libaluleke kakhulu ekubumbeni ikusasa lokuqamba kabusha nokutholwa.
