Ingxoxo
Ukufaka ugesi ngokuhlikihla kwenziwa ngokuhlikihla ugesi entweni ezofakwa ugesi, lapho ukuhlikihla kwenziwa ngakolunye uhlangothi. Izingongolo ezakhiwe entweni efakwe ugesi zincike engotsheni yogesi esetshenziselwa ukuhlikihla. Uma ingotshe yogesi esetshenziselwa ukuhlikihla iyingotshe yasenyakatho, khona-ke ukuphela kwento ehlikihlayo kuba yingotshe yaseningizimu. Ngokuphambene nalokho, uma ingotshe yogesi esetshenziselwa ukuhlikihla iyingotshe yaseningizimu, khona-ke ukuphela kwento ehlikihlayo kuba yingotshe yasenyakatho.

Ingxoxo
Isithombe esiseceleni siyisibonelo se-solenoid egeleza. ugesi wamanjeI-solenoid iyi-coil yocingo enokujika okuningi. Uma ugesi ugeleza nge-solenoid, ukhiqiza insimu yamagnetic, lapho izigxobo zamagnetic zingabonakala khona kusetshenziswa umthetho wesandla sokudla.
Insimu yamagnetic ekhiqizwa yi-solenoid inesigxobo sasenyakatho nesaseningizimu, njengensimu yamagnetic yamagnet yemvelo. Uma into igoqwe nge-solenoid ukuze yenziwe imagnet, insimu yamagnetic yaleyo nto izoba njengensimu yamagnetic ekhiqizwa yi-solenoid. Uma into iyisilinda, iba yimagnet eyisilinda. Uma into injengenduku, iba yimagnet yebha. Ukwenza imagnet ngale ndlela kubizwa ngokuthi imagnetization ngokudlulisa ugesi kuyo.
Ngakho-ke insimu yamagnetic ku-solenoid enikezwa ugesi iyafana nensimu yamagnetic kumagnet webha noma kumagnet we-cylindrical.
Izimpendulo ezifanele ngu-B no-C.

Impendulo efanele ngu-C.
6. Chaza izindlela ezintathu zokwenza umazibuthe!
Ingxoxo
1. Ukuhlikihla insimbi ngemagnet
Ukufaka ugesi ngokuhlikihla kwenziwa ngokuhlikihla ugesi entweni ezofakwa ugesi, lapho ukuhlikihla kwenziwa ngakolunye uhlangothi. Izingongolo ezakhiwe entweni efakwe ugesi zincike engotsheni yogesi esetshenziselwa ukuhlikihla. Uma ingotshe yogesi esetshenziselwa ukuhlikihla iyingotshe yasenyakatho, khona-ke ukuphela kwento ehlikihlayo kuba yingotshe yaseningizimu. Ngokuphambene nalokho, uma ingotshe yogesi esetshenziselwa ukuhlikihla iyingotshe yaseningizimu, khona-ke ukuphela kwento ehlikihlayo kuba yingotshe yasenyakatho.
2. Ukuletha insimbi eduze kwemagnethi (indlela yokungenisa)
Ukwenziwa kogesi ngokungenisa kuhilela ukuletha into ukuze ifakwe ugesi eduze kwento esivele ixhunywe ugesi, ngaphandle kokuthinta izinto ezimbili. Uma umkhawulo owodwa wento ulethwa eduze kwensika esenyakatho yemagnethi, uba yinsika eseningizimu. Ngokuphambene nalokho, uma umkhawulo wento ulethwa eduze kwensika eseningizimu, uba yinsika esenyakatho.
3. Ugesi ogeleza ngensimbi
Inqubo yokwenza uzibuthe ngokudlulisa ugesi kuwo iboniswe esithombeni esingezansi. Izigxobo zikamazibuthe eziphumayo zinqunywa kusetshenziswa umthetho wesandla sokudla. Beka isandla sakho sokudla siqonde phambi kobuso bakho, intende yakho ibheke ubuso bakho. Goba iminwe yakho emine (uphawu, iphakathi, indandatho, kanye neminwe emincane). Isiqondiso seminwe yakho emine sifana nesiqondiso somsinga ku-coil yentambo, futhi isiqondiso sesithupha sakho ngakwesokudla sifana nesiqondiso sensimu kazibuthe. Insimu kazibuthe ihlala ikhomba kusukela empondweni osenyakatho iye empondweni oseningizimu. Ngakho-ke, esithombeni C, ukuphela B kuyimpondo esenyakatho yomazibuthe, kanti ukuphela A kuyimpondo eseningizimu yomazibuthe.
7. Ibha yensimbi izokwenziwa ibe yimagnethi ngendlela eboniswe esithombeni esingezansi.
Izinsika ezisebenza ngogesi ezitholakala endukwini yensimbi….

Isithombe esingenhla sibonisa indlela yokwenza i-magnet ngokuhlikihla.
Ukuziba ngokucindezela kuhilela ukuhlikihla uziba ngento ezoziba ngokucindezela, lapho ukuhlikihla kwenziwa ngakolunye uhlangothi. Izingongolo ezakhiwe entweni eziba ngokucindezela zincike ezingongolweni zikaziba ezisetshenziselwa ukuhlikihla.
Uma i-magnetic pole esetshenziselwa ukuhlikihla iyi-north pole, khona-ke ukuphela kokugcina kwento ehlikihlayo kuba yi-southern pole. Ngakolunye uhlangothi, uma i-magnetic pole esetshenziselwa ukuhlikihla iyi-southern pole, khona-ke ukuphela kokugcina kwento ehlikihlayo kuba yi-north pole.
Esithombeni esingenhla, i-south pole isetshenziselwa ukuhlikihla ukuze u-B = i-north pole kanye no-A = i-south pole.

Ingxoxo
Isithombe esingenhla sibonisa indlela insimbi eyenziwa ngayo ibe yimagnet ngokudlulisa ugesi kuyo. Insimbi iyinto eqinile edonsa amandla kazibuthe, okusho ukuthi uma idonsa amandla kazibuthe, iba yimagnet ehlala njalo. Insimbi, isibonelo, iyisibonelo sezinto ezithambile ezidonsa amandla kazibuthe, okusho ukuthi uma idonsa amandla kazibuthe, iba yimagnet yesikhashana.
Ngokusekelwe esithombeni esingenhla, ugesi ugeleza usuka kumandla aphezulu uye kumandla aphansi (kusuka kwesobunxele uye kwesokudla). Izigxobo zikagesi zaziwa ngokusebenzisa umthetho wesandla sokudla. Yelula isandla sakho sokudla, usibeke ngendlela yokuthi intende yesandla sokudla ibheke ubuso bakho. Yelula isithupha sakho bese ugoba eminye iminwe emine phambili ubheke ebusweni bakho. Isiqondiso sokugoba kweminwe emine sifana nesiqondiso sokugeleza kogesi ku-coil, kuyilapho isithupha sikhomba esigxotsheni esisenyakatho sensimu kagesi. Isithupha sikhomba ku-B, ngakho-ke u-B uyinsika esenyakatho yemagnethi kanti u-A uyinsika eseningizimu yemagnethi.
Impendulo efanele ngu-C.

Isithombe esikwesobunxele sibonisa indlela i-magnet enziwa ngayo ngokudlulisa ugesi kuyo. Ugesi ugeleza usuka ku-high potential uye ku-low potential (kusukela kwesobunxele se-coil uye kwesokudla se-coil). Isiqondiso sensimu yamagnetic ephumayo kanye nesiqondiso sezinsika zamagnetic kunganqunywa kusetshenziswa umthetho wesandla sokunene.
Yelula isandla sakho sokunene, usibeke ngendlela yokuthi intende yesandla sakho sokunene ibheke ubuso bakho. Lungisa isithupha sakho bese ugoba eminye iminwe emine phambili ibheke ebusweni bakho. Indlela yokugoba kweminwe emine ifana nendlela yokugeleza kwamandla kagesi kukhoyili, kuyilapho isithupha sikhomba epalini elisenyakatho lensimu yamagnetic. Isithupha sikhomba ku-N ukuze u-N abe yipali esenyakatho yamagnethi kanti u-M abe yipali eseningizimu yamagnethi. U-N no-O bayaphikisana ngakho-ke u-N no-O banepali efanayo, okungukuthi ipali esenyakatho. Uma u-O eyipali esenyakatho khona-ke u-P uyipali eseningizimu.
Ngokusekelwe encazelweni engenhla, kungaphethwa ngokuthi:
M = i-South Pole (S)
N = i-north pole (U)
O = i-north pole (N)
P = i-south pole (S)

Isithombe esingenhla sibonisa indlela i-magnet enziwa ngayo ngokudlula ugesi kuyo. Insimbi edonsa i-magnet iyinsimbi. Insimbi iyinto eqinile edonsa i-magnet; uma idonsa i-magnet, iba i-magnet ehlala njalo.
Ngokusekelwe esithombeni esingenhla, ugesi ugeleza usuka kumandla aphezulu uye kumandla aphansi (kusukela kwesobunxele sekhoyili uye kwesokudla sekhoyili).
Izingongolo zikamazibuthe zibonakala kusetshenziswa umthetho wesandla sokudla. Yelula isandla sakho sokudla ukuze intende yakho ibheke ubuso bakho. Yelula isithupha sakho bese ugoba eminye iminwe emine phambili ebusweni bakho. Isiqondiso sokugoba kweminwe emine sihambisana nesiqondiso sokugeleza kwamandla kagesi kukhoyili, kuyilapho isithupha sikhomba esigxotsheni esisenyakatho sensimu yamagnetic. Isithupha sikhomba ku-Q, ngakho-ke u-Q umelela isigxobo esisenyakatho sikamazibuthe kanti u-P umelela isigxobo esiseningizimu sikamazibuthe.
