Amandla eMagnet alinganiswa njani?

Iimagnethi bezizinto ezinomdla kangangeenkulungwane, zitsala izazinzulu kunye nabantu abathanda izinto ngesakhono sazo esingaqondakaliyo sokutsala izinto ezithile. Ukususela kwiinaliti zekhampasi ezikhokela abahloli bamandulo ukuya kwiinkqubo ezintsonkothileyo zobuchwepheshe banamhlanje, iimagnethi zidlala indima ebalulekileyo kwiinkalo ezahlukeneyo zobomi bethu. Kodwa singazilinganisa njani amandla ezi zinto?amasimi emagnethiSilinganisa njani amandla emagnethi? Makhe sijonge iindlela nezixhobo ezisetyenziswayo ukulinganisa amandla emagnethi.

Amandla eMagnetic Field

Amandla emagnethi axhomekeke ngokusisiseko kumandla ayo emagnethi, indawo ejikeleze imagnethi apho impembelelo yayo ivakala khona. Le ntsimi imelwe yimigca yamandla, eqala kwi-entla pole yemagnethi ukuya kwi-esezantsi pole yayo. Okukhona uxinano lwezi migca lukhulu, kokukhona i-magnetic field inamandla ngakumbi.

UGauss kunye noTesla: IiYunithi zoMlinganiselo

Ukuze balinganise amandla emagnethi, izazinzulu zisebenzisa iiyunithi ezimbini eziphambili zokulinganisa: uGauss kunye noTesla.

UGauss (G): Eli candelo libizwa ngegama lesazi sezibalo kunye nefiziksi saseJamani uCarl Friedrich Gauss, lilinganisa uxinano lwe-magnetic flux okanye i-magnetic induction. I-Gauss enye ilingana ne-Maxwell enye ngesentimitha yesikwere. Nangona kunjalo, ngenxa yobukhulu obuncinci be-Gauss, ngakumbi kwiimeko zanamhlanje, izazinzulu zihlala zisebenzisa i-Tesla kwiindawo ezinamandla ze-magnetic.

ITesla (T): Le yunithi, ebizwa ngegama lokuhlonipha umsunguli waseSerbia-waseMelika kunye nonjineli wombane uNikola Tesla, imele uxinano olukhulu lwe-magnetic flux xa ithelekiswa neGauss. I-Tesla enye ilingana ne-10,000 Gauss, nto leyo eyenza ukuba ibe yiyunithi esebenzayo ngakumbi yokulinganisa amasimi e-magnetic aqinileyo, njengalawo aveliswa ziimagnethi ezinamandla ezisetyenziswa kuphando lwesayensi okanye kwizicelo zoshishino.

Iimagnetometer

Iimagnetometer zizixhobo ezenzelwe ukulinganisa amandla kunye necala leemagnethi. Ezi zixhobo ziza ngeendlela ezahlukeneyo, ukusuka kwiikhampasi ezilula eziphathwayo ukuya kwizixhobo zelebhu ezintsonkothileyo. Nazi ezinye zeentlobo eziqhelekileyo zeemagnetometer ezisetyenziselwa ukulinganisa amandla emagnethi:

1. Iimagnetometer zeFluxgate: Ezi magnetometers zisebenzisa imigaqo yokungeniswa kwe-electromagnetic ukulinganisa utshintsho kwiindawo zemagnethi. Ziqulathe i-core enye okanye ezingaphezulu ze-magnetic ezijikelezwe zii-coils ze-wire. Xa zibekwe kwindawo yemagnethi, ii-cores ziba yi-magnetized, nto leyo ebangela isignali yombane kwiikhoyili, ezinokulinganiswa kwaye zilinganiswe ukuze kuchongwe amandla e-magnetic field.

2. Iimagnetometer zeHall Effect: Iimagnetometer zempembelelo yeHall zixhomekeke kwimpembelelo yeHall, echaza ukuveliswa komahluko wevolthi (ivolthi yeHall) kwi-conductor yombane xa iphantsi kwe-magnetic field ethe nkqo kumlambo wangoku. Ngokulinganisa le voltage, iimagnetometer zempembelelo yeHall zinokumisela amandla e-magnetic field.

3. Iimagnetometer zeSQUID: Iimagnetometer zeSuperconducting Quantum Interference Device (SQUID) ziphakathi kweemagnetometer ezibuthathaka kakhulu ezikhoyo. Zisebenza ngokusekelwe kwiimpawu zequantum zeesuperconductors, ezivumela ukuba zibone amasimi emagnethi abuthathaka kakhulu, ukuya kuthi ga kwinqanaba le-femtoteslas (10^-15 Tesla).

Ukulinganisa kunye nokuMisela

Ukuqinisekisa ukulinganisa okuchanekileyo, iimagnetometer kufuneka zilinganiswe ngokufanelekileyo kwaye zibekwe emgangathweni. Ukulinganisa kubandakanya ukuthelekisa imveliso yemagnetometer namandla entsimi yemagnethi aziwayo ukuze kusekwe ulwalamano oluthe ngqo phakathi kokufundwa kwesixhobo kunye namaxabiso entsimi yemagnethi yokwenyani. Ukulinganisa kuqinisekisa ukuba ukulinganisa okuthathwe ngeemagnetometer ezahlukeneyo kuyahambelana kwaye kuyalingana.

Ukusetyenziswa kweMagnetometry

Ukukwazi ukulinganisa amandla entsimi yamagnetic ngokuchanekileyo kunezicelo ezininzi kwiindawo ezahlukeneyo:

I-GeophysicsIimagnetometer zisetyenziselwa ukufunda intsimi yemagnethi yoMhlaba, enika ulwazi oluxabisekileyo malunga nolwakhiwo kunye nokwakheka kwengaphakathi leplanethi.

Ukuhambahamba: Iikhampasi, uhlobo lwemagnetometer, bezisoloko zizixhobo ezibalulekileyo zokuhamba ngenqanawa ukususela kumaxesha amandulo, zinceda oomatiloshe kunye nabahloli bamazwe ukuba bafumane indlela yabo yokudlula kwiilwandle ezinkulu.

Isayensi yezixhoboI-Magnetometry isetyenziselwa ukuchazaizixhobo zemagnethikwaye bafunde iimpawu zabo, ezibalulekileyo kuphuhliso lwetekhnoloji efana nezixhobo zokugcina izinto ezisebenzisa imagnethi kunye noomatshini be-magnetic resonance imaging (MRI).

Ukuhlola IsithubaIimagnetometers zisetyenziswa kwi-spacecraft ukuze zifunde amasimi emagnethi ezidalwa zasezulwini, zibonelela ngolwazi malunga nokwakheka kwazo kunye nembali yejoloji.

Isiphelo

Ukulinganiswa kwamandla emagnethi kubalulekile ekuqondeni indlela ezisebenza ngayo iimagnethi kunye nokusetyenziswa kwazo kwiindawo ezahlukeneyo. Ngokusebenzisa iiyunithi ezifana neGauss kunye neTesla kunye nezixhobo ezifana neemagnethi, izazinzulu zinokubala ngokuchanekileyo amandla emagnethi, zivula indlela yokuqhubela phambili kubuchwepheshe, uphando, kunye nophando lwesayensi. Njengoko ukuqonda kwethu ngemagnethi kuqhubeka nzulu, kuya kuba njalo nokukwazi kwethu ukusebenzisa amandla ayo ukuze kuzuze uluntu.
