Molo apho! Wakhe wadlala ngeemagnethi? Bapholile ngokwenene, akunjalo? Ungazifaka efrijini yakho okanye uzisebenzise ukuklipha amaphepha kunye. Kodwa ngaba uyazi ukuba yintoni ebenza baphawule? Ke ngoku, masingene kulonwabo lweemagnethi!
Amandla emagnethi ngamandla akhethekileyo emagnethi. Icacisa ukuba kutheni iimagnethi zinokuncamathelana okanye zigxothane. La mandla aveliswa ngamasuntswana amancinane aziwa ngokuba zii-electron anokufumaneka kwizinto ezithile. Ezi ziquka izixhobo ze-ferromagnetic ezifana nentsimbi, i-cobalt, kunye ne-nickel. Ezi ntlobo zemathiriyeli zibizwa ngokuba yi-ferromagnetic materials kuba ziyakwazi ukuba ziimagnethi. Olu lungelelwaniso lwee-electron ludala oko kubhekiselwa kuko njengemagnethi ejikeleze loo nto xa ibekwe ngendlela ethile. Lo mhlaba wemagnethi yeyona nto yenza iimagnethi zibe namandla kwaye kumnandi ukudlala ngazo!
Imagnethi inamacala amabini abizwa ngokuba ziipali. Esinye isiphelo sisibonda esingasentla, esinye isiphelo sisibonda sasezantsi. Xa sisondeza oomazibuthe ababini-(zombini zine-N kunye ne-S pole) kukho into enika umdla eyenzekayo! Izixhobo ezineepali ezichaseneyo, ezifana ne-North pole kunye ne-South pole, zitsala enye kwenye. Oko kubizwa ngokuba ngumtsalane, kwaye kwenza iimagnethi zincamathele enye kwenye. Kodwa ukuba uzama ukudibanisa izibonda ezimbini, njengezibonda ezimbini zasentla, ziyangqubana. Oku kubizwa ngokuba kukugxotha. Yiyo loo nto iimagnethi zinokuncamathela kwizinto zentsimbi ezifana nefriji yakho okanye i-paperclip. Oko kuthetha ukuba oomazibuthe bakhona kuyo yonke indawo kubomi bethu bemihla ngemihla! Yitsho ukuba, umzekelo, udibene nekhampasi. Ikhampasi sisixhobo esincinci esisebenzisa umazibuthe ukufumanisa indlela esempuma. Ewe, iluncedo kakhulu kubantu abaphononongayo okanye nokuhamba intaba. Iimagnethi zikwasetyenziswa kwiinjini kunye neejenereyitha, ezivelisa umbane oxhobisa amakhaya ethu kunye nezixhobo zethu ezininzi.
Ixesha lokufunda: 4 imizuzu Ubusazi ukuba iimagnethi zazisetyenziswa ngabantu ukunyanga izifo ukusukela kumaGrike amandulo? AmaGrike amandulo afumanisa iimagnethi kumawaka eminyaka eyadlulayo kwaye asebenzisa ilitye lendalo elibizwa ngokuba yimagnetite. Babekholelwa ukuba lilitye lomlingo! Kodwa abantu khange baqalise ukuqonda ngokwenyani indlela osebenza ngayo oomazibuthe de kwaba ngoo-1800. Ngenkulungwane ye-19, iimagnethi zaphononongwa ngokungqongqo ngakumbi kwaye izazinzulu zaqala ukufunda ngazo kunye neempawu zazo. Kwaze ngeminyaka yee-1900, izazinzulu zakhupha iimagnethi ezinamandla. Namhlanje, ezi magnethi zinamandla zisetyenziswa koomatshini abaninzi ababalulekileyo, umzekelo oomatshini beMRI. Oomatshini be-MRI bavumela oogqirha ukuba babone ngaphakathi emzimbeni wakho ngaphandle kokusikeka. Basebenzisa oomazibuthe ukwenza imifanekiso eneenkcukacha yento eyenzekayo ngaphakathi kuwe, kwaye oko kunokuba luncedo kakhulu koogqirha ukwazi ukuba banyange njani izigulana.
I-Cobalt: Le yimathiriyeli eyomeleleyo enokuthi ibambe i-magnetism eninzi kodwa kukho ixabiso elibi kakhulu sesinye sezizathu zokuba isetyenziswe kancinci kwimagnethi yemihla ngemihla.
I-Neodymium: Esi sisizukulwana esitsha semagnethi kwaye zinamandla kakhulu, ngaphezu kwentsimbi kunye necobalt. Imagnethi ye-Neodymium inokufumaneka kwizixhobo ezininzi zanamhlanje - kubandakanywa (kodwa kungaphelelanga) ii-headphones kunye nee-injini zomoya, ezinegalelo ekuveliseni amandla acocekileyo.
Izazinzulu zihlala zikhangela iindlela zokwenza itekhnoloji entsha, kwaye iimagnethi ziyinxalenye enkulu yazo. Enye indlela enika umdla yophando lubushushu obuphezulu obuphezulu. Oku kubonisa ukuba into inokuvumela umbane ukuba uhambe ngaphandle kokuchithwa kwiqondo lokushisa eliphezulu. Ukuba izazinzulu zinokufunda ukwenza oku, ngeemagnethi, inokuba yinto engakholelekiyo! Khawufane ucinge aba loliwe bakhawulezayo ngokwenene bandanda phezu kwendlela besebenzisa iimagnethi ukuze bafike apho baya khona - kwaye bangachukumisi umhlaba ngesantya esiphezulu. Okanye khawucinge ngezikhuselo ezinozibuthe ezinokukhusela iziphekepheke kwimitha yeayoni esemajukujukwini. Kwaye kungekudala, kwanokuhamba emajukujukwini kuya kutshintsha ngale nkqubela!
