Informatec Digital » Intelligence yokufakelwa » I-Electromagnetism empilweni yansuku zonke

I-Electromagnetism ingamandla ayisisekelo emvelo akhona cishe kuzo zonke izici zokuphila kwethu kwansuku zonke. Kusukela ezintweni zikagesi esizisebenzisayo kuye entuthukweni yezokwelapha esigcina sinempilo, uzibuthe kagesi udlala indima ebalulekile ezimpilweni zethu zansuku zonke. Kulesi sihloko, sizogxila ezibonelweni ze-electromagnetism ekuphileni kwansuku zonke.

Izibonelo eziyi-10 ze-electromagnetism ekuphileni kwansuku zonke

1. Ukuxhumana

Omakhalekhukhwini

Omakhalekhukhwini basebenzisa amaza kagesi ukudlulisa nokwamukela izimpawu zezwi nedatha. Lawa maza ahamba emoyeni futhi athathwa yizinzwane zocingo, okusivumela ukuthi sixhumane nabantu noma kuphi emhlabeni. Ngaphandle kwe-electromagnetism, omakhalekhukhwini bebengeke babe khona.

Internet

I-inthanethi isuselwe ekudluliselweni kwedatha ngamakhebula namagagasi kagesi. Lapho sithumela i-imeyili noma sivakashela iwebhusayithi, idatha idluliselwa ngesimo samasignali kazibuthe kagesi ngezintambo ze-fiber optic noma ngamaza omsakazo. Ngenxa ye-electromagnetism, singakwazi ukufinyelela inani elikhulu lolwazi futhi sixhumane nabantu emhlabeni jikelele.

ithelevishini nomsakazo

Ithelevishini nomsakazo nakho kuncike ku-electromagnetism ukuze kusebenze. Izimpawu zikamabonakude nezomsakazo zisakazwa ngendlela yamaza kazibuthe kagesi ahamba emoyeni futhi athathwe yizimpondo zemishini yethu yokwamukela. Ngaphandle kwe-electromagnetism, besingeke sikwazi ukujabulela izinhlelo esizithandayo noma ukulalela umculo emsakazweni.

2. Izinto zikagesi

I-Microwave

Ohavini be-Microwave basebenzisa amaza kagesi ukushisisa ukudla. Lawa maza abangela ama-molecule amanzi ekudleni anyakaze, akhiqize ukushisa futhi apheke ukudla ngokushesha nangempumelelo. I-electromagnetism iguqule indlela esishisisa ngayo nesilungisa ngayo ukudla kwethu.

Iziqandisi

Iziqandisi zisebenzisa uzibuthe kagesi ohlelweni lwazo lokupholisa. I-compressor yesiqandisi, empeleni eyinjini kagesi, isebenzisa amandla kazibuthe ukuze icindezele futhi ijikeleze isiqandisi, igcine ukudla kwethu kukusha futhi kusesimweni esihle.

Imishini yokuwasha kanye nemishini yokomisa

Imishini yokuwasha nokomisa nakho kuncike ku-electromagnetism ukuze isebenze. Izinjini zikagesi kulezi zixhobo zisebenzisa amandla kazibuthe ukuphotha izigubhu futhi zihlanze noma zomise izingubo zethu. Ngaphandle kwe-electromagnetism, imisebenzi yasekhaya ingaba isidina kakhulu futhi idinga umzamo owengeziwe wezandla.

3. Ezokuthutha

Ama-motors kagesi

Amamotho kagesi, atholakala ezimotweni eziningi ezihlukene kusukela ezimotweni zikagesi kuya ezitimeleni nasezindlini, zisebenzisa uzibuthe kagesi ukuguqula amandla kagesi abe ukunyakaza.

I-Electromagnetism ivumela lezi zitimela ukuthi zifinyelele isivinini esimangalisayo ngokungqubuzana okuncane.

Amasistimu wokuzulazula we-GPS

Izinhlelo zokuzulazula ze-GPS (Global Positioning System) zisebenzisa izimpawu zikagesi ezithunyelwa ngamasathelayithi ukuze kutholakale indawo yomamukeli eMhlabeni. Lezi zimpawu zihamba ngesivinini sokukhanya futhi zithathwa yisamukeli se-GPS, esibala indawo yaso ngokusekelwe esikhathini esithathayo ukuze izimpawu zifike zivela kumasathelayithi. I-Electromagnetism yenza kube nokwenzeka ukuzulazula okunembile, ngesikhathi sangempela.

4. Umuthi

I-Magnetic resonance imaging (MRI)

I-Magnetic resonance imaging (i-MRI) isebenzisa amandla kazibuthe namaza omsakazo ukuze idale izithombe ezinemininingwane yengaphakathi lomzimba. Phakathi ne-MRI, ama-athomu e-hydrogen emzimbeni ahambisana namandla kazibuthe abese eshukunyiswa amaza omsakazo, akhiphe amasignali athathwa yisithwebuli bese esetshenziselwa ukwakha izithombe. I-Electromagnetism iguqule ukuxilongwa kwezokwelapha ngokuvumela odokotela ukuthi babone ngaphakathi emzimbeni ngaphandle kokuhlinzwa.

I-Electrocardiograms (ECG)

Ama-Electrocardiograms (ECGs) asebenzisa ama-electrode abekwe esikhunjeni ukukala ukusebenza kukagesi kwenhliziyo. Lezi zibonakaliso zikagesi zikhiqizwa isimiso sokuhamba kukagesi senhliziyo, esisekelwe ekugelezeni kwama-ion ngolwelwesi lwamaseli. Ama-ECG ayithuluzi elibalulekile lokuhlola izinkinga zenhliziyo nokuqapha impilo yenhliziyo.

I-Transcranial magnetic stimulation (TMS)

I-Transcranial magnetic stimulation (TMS) iyindlela engahlaseli esebenzisa izinkambu kazibuthe ukuvuselela izindawo ezithile zobuchopho. Phakathi ne-TMS, ikhoyili kagesi ibekwa eduze kwesikhumba, ikhiqize insimu kazibuthe eyenza amandla kagesi ebuchosheni. Le nqubo isetshenziselwa ukwelapha izifo ezinjengokucindezeleka, i-obsessive-compulsive disorder kanye nesifo sikaParkinson.

5. Amandla

Amajeneretha kagesi

Amajeneretha kagesi asebenzisa uzibuthe kagesi ukuguqula amandla emishini abe amandla kagesi. Kujeneretha, uzibuthe uzungeza ngaphakathi kwekhoyili yocingo, efaka amandla kagesi ocingweni. Lesi sakamuva singase sisetshenziselwe ukunika amandla amakhaya, amabhizinisi kanye nezimboni. I-Electromagnetism ekuphileni kwansuku zonke ibonakala ngokucacile ekusebenzeni kwansuku zonke kwalawa ma-generator, abalulekile ekuhlinzekeni kwamandla kagesi esiwasebenzisa nsuku zonke.

Izinguquko

Ama-Transformer ngamadivayisi asebenzisa i-electromagnetism ukushintsha i-voltage yamanje kagesi. Ahlanganisa amakhoyili amabili amanxeba ocingo azungeze umongo wensimbi. Lapho umsinga oshintshashintshayo udlula kwenye yamakhoyili, uheha inkambu kazibuthe enkabeni, yona ibangele umsinga kwenye ikhoyili. Ama-transformer abalulekile ekusabalaliseni kahle kwamandla kagesi ebangeni elide. Le nqubo iphinde igqamise umthelela kazibuthe kagesi empilweni yansuku zonke, yenza kube lula ukulethwa kukagesi odingekayo emisebenzini nezinsizakalo ezahlukahlukene.

Imigqa yokudlulisela

Imigqa yokudlulisa isebenzisa uzibuthe kagesi ukuthutha amandla kagesi ebangeni elide. Le migqa iqukethe amakhebuli ekhondatha amiswe emibhoshongweni yamandla kagesi aphezulu. Umsinga kagesi ogeleza kulezi zintambo ukhiqiza izizibuthe, ezibangela imisinga ezintanjeni eziseduze. Le nqubo ivumela amandla kagesi ukuthi athuthwe kahle esuka ezitshalweni zikagesi aye emakhaya nasemabhizinisini. Ngakho-ke, i-electromagnetism ekuphileni kwansuku zonke ibonakala engqalasizinda esekela ukufinyelela kwethu kwansuku zonke nokuthembekile kwamandla kagesi.

6. Ezokuzijabulisa

izipikha nama-headphone

Izipikha nama-headphone asebenzisa uzibuthe kagesi ukuguqula amasignali kagesi abe amaza omsindo. Ahlanganisa uzibuthe unomphela kanye nekhoyili yocingo exhunywe ku-diaphragm. Lapho amandla kagesi edlula kukhoyili, akhiqiza amandla kazibuthe asebenzisana nozibuthe ongapheli, okwenza i-diaphragm idlidlize futhi ikhiphe umsindo.

Umabonakude kanye nezikrini zekhompyutha

Izikrini zikamabonakude nezekhompyutha zisebenzisa i-electromagnetism ukuze zenze izithombe. Emibukisweni ye-CRT (cathode ray tube), i-electron beam iqondiswe esikrinini esimbozwe i-phosphor ngezinkundla kazibuthe, okubangela ukuthi i-phosphor ikhanye futhi yakhe isithombe. Kuzikrini ze-LCD (i-liquid crystal display) ne-OLED (organic light-emitting diode) izikrini, izinkambu zikagesi zilawula umumo wamakristalu awuketshezi noma ukuphuma kokukhanya kwama-diode, kwakheka isithombe.

Amadrayivu aqinile namadrayivu wesimo esiqinile

Amadrayivu aqinile namadrayivu e-solid-state asebenzisa uzibuthe kagesi ukuze agcine futhi athole idatha. Kuma-hard drive, idatha igcinwa kumadiski kazibuthe azungezayo futhi ifinyelelwa ngokufunda/ukubhala amakhanda azwayo futhi aphathe izinkambu kazibuthe ebusweni bediski. Kumadrayivu esimo esiqinile, idatha igcinwa kuma-flash memory chips, kodwa inqubo yokufunda nokubhala isabandakanya ukukhohliswa kwezindleko zikagesi.
