Insimu yamagnetic yamanje

Ukutadisha izimo ezihlukahlukene zamagnetic kubonise ukuthi yonke indawo, lapho kukhona khona ugesi kagesi, i.e. Amacala kagesi ahambayo, kukhona nensimu yamagnetic yamanje.

Ngenxa yokuthi insimu yamagnetic isakhiwe nxazonke zomqhubi, uma i-current ivela kulokhu okugcina, ngokuvamile ibhekwa njengomthombo wokwakhiwa kwensimu yamagnetic. Ngalo mqondo, ibizwa ngokuthi "inkundla yamagnetic yamanje".

Ukuqondiswa kwalo kuxhomeke ekuqondeni kwamandla kagesi okuzovela kulokhu kuvela.

Ukutholakala kwensimu yamagnetic eduze komqhubi onamandla kagesi kungatholakala ngezindlela eziningana. Enye yalezi zindlela ukusetshenziswa kwezinsimbi ze-iron. Ngesinye isikhathi ensimini yamagnetic yamanje, izingcezu zensimbi, lapho kuhlanganiswa khona izinsimbi zensimbi, ziba imicibisholo encane yamagnetic. Ngamunye wale micibisholo ensimini yamagnetic isethwe ukuze i-axis yayo ihambelane ne-orientation yensimu yamagnetic endaweni lapho itholakala kuyo. Ngosizo lwemicibisholo eminingi enjalo, umuntu angabona indlela ukuqondisa kwamandla okwenza ngayo insimu yamagnetic kuyashintsha njengoba umuntu ehamba esuka endaweni eyodwa ensimini kuya kwesinye. Ukuhlelwa okunjalo emkhakheni wamagnetic wamanje wezinsimbi ze-iron kuthiwa yi-spectrum magnetic.

Sizosebenzisa i-sawdust yamagnetic futhi sicabangele insimu yamagnetic yosuku lwamanje. Ukuze senze lokhu, ake sidlule umqhubi ngomshini wekhadibhodi, bese ugcwalisa amakhadibhodi ngezingqimba ezincane zensimbi. Siyabona ukuthi uma okwamanje kugeleza umqhubi, i-sawdust izobekwa kuyo nxazonke emibuthanweni eqondile.

Imigqa, ngokusho ukuthi insimu yamagnetic yamanje inezinhlayiya zemicibisholo emincane yamagnetic, ibizwa ngokuthi imigqa yayo yamandla. Ngosizo lwemigqa yamandla kulula kakhulu ukubonisa imidwebo yamagnetic ngokucacile.

Umzila wamandla uhanjiswa ukuze umzila okhanyayo kuwo noma nini ukhombise ukuqondiswa kwamandla okwenza kuleli phuzu kuya enyakatho.

Amaketanga ahlanganiswe emkhakheni wamagnetic we-current ngokusebenzisa ama-iron filings abonisa ukuthi yimaphi imigqa yamandla emkhakheni wamagnetic.

Imigqa yamandla emkhakheni wamagnetic ivinjiwe ama-curve azungeze umqhubi. Ngokuyinhloko, imigqa yamanje yamandla magnetic linezingxenyana ezigxilwe kuzo izikhungo zazo ezisemgqeni wamanje.

Ukunquma ukuqondiswa kwemigqa yamandla kagesi ngokuphathelene nokuqondiswa kwamanje, esikhundleni se-sawdust, sebenzisa imicibisholo yamagnetic. Njengoba besizungezile nomqhubi nge-current, sinquma ukuqondiswa kwemigqa yamandla. Uma ukuma kwamanje kumqhubi kuyashintsha okuphambene nalokho, imicibisholo yamagnetic ijika 180 °, ekhombisa ushintsho oluhambelana nokuqondisa kwemigqa yasensimu.

Ukuqondiswa kwemigqa yamandla emkhakheni wamagnetic kuhlobene nokuqondiswa kwamanje kumqhubi ngomthetho olula ohlongozwa ngumsayense waseNgilandi uMaxwell: uma ukunyakaza kokuhumusha kwenkomba yokugaya kuhambelana nokuqondisa kwamanje kumqhubi, khona-ke ukuqondisa kokujikeleza kwesibambo senkinobho kuhambelana nokuqondiswa kwemigqa yamandla emkhakheni wamagnethe nxazonke Umqhubi.

Lo mthetho ngezinye izikhathi ubizwa ngokuthi umthetho we-gimlet.

Masihambe manje uthathe umqhubi ohamba nge-circumference, futhi esivumela ukudlula okwamanje, sizophinde siphinde sibheke ukulungiswa kwe-sawdust ekhadini, kufakwe ngokulandelana kwendiza yendilinga. Sithola ukuthi imigqa yamandla kagesi ayisekho imibuthano evamile, kodwa kulokhu wonke imigqa ivaliwe, ngokuphambana nomqhubi lapho igeleza khona manje. Ngakho-ke, imigqa yamandla kagesi ihlala iseduze eduze kwamanje.

Ngokubeka imicibisholo yamagnetic amancane amaphuzu ahlukene kule nsimu, umuntu anganquma ukuqondiswa kwemigqa yamandla yasensimu.

Ukubusa kwe-borer kuyasebenza , okwamanje, kumanje oyisiyingi, kodwa kulokhu kuyinto elula kakhulu ukushintshanisa isiqondiso sendawo yamanje namagnetic. Ngempela, uma isibambo se-borer sijikelezwa njengamanje, ukuhamba kwetiphu zalo kuzokubonisa ukuthi iyiphi insimu ye-magnetic yesimiso esisiyingi.
