1. Bheka isithombe! Lapho i-south pole ingena ku-coil, inaliti ye-galvanometer iyahamba iye...
A. kwesokudla bese kwesobunxele
B. khona-ke kuya ku-zero
C. kwesobunxele bese kwesokudla
D. kwesokunxele bese kuba yi-zero
Ingxoxo
Ngaphambi kokufunda le ncazelo, kubalulekile ukuqonda kuqala umthetho wesandla sokudla. Yelula isandla sakho sokudla, uqondise isithupha sakho, bese ugoqa eminye iminwe yakho emine. Uma isithupha sikhomba ohlangothini logesi, khona-ke ukujikeleza kweminye iminwe emine kubonisa indlela yensimu yamagnetic. Ngokufanayo, uma ukujikeleza kweminwe emine kubonisa indlela yogesi, khona-ke isithupha sibonisa indlela yensimu yamagnetic.
Inaliti ye-galvanometer iya kwesokudla uma ugesi ugeleza uye kwesokudla kwesekethe, uye ohlangothini lokujikeleza kwewashi kanye nenaliti ye-galvanometer iya ngakwesokunxele uma ugesi ugeleza uye kwesobunxele kwesekethe, uye ohlangothini lokujikeleza okuphikisana newashi.
Umthetho kaLenz uthi i-EMF ebangelwayo ihlala ikhiqiza ugesi onensimu yamagnetic ephambene nesiqondiso sokushintsha kokuguquguquka. Ngakho-ke uma i-pole eseningizimu yemagnethi ingena phansi ku-coil, kukhiqizwa ugesi onensimu yamagnetic ephambene nesiqondiso sokunyakaza kwemagnethi. Kusetshenziswa umthetho wesandla sokunene, ukuze insimu yamagnetic ebangelwayo iqondiswe phezulu (isiqondiso esifanayo nesithupha), ugesi obangelwayo kumele ugeleze uye kwesobunxele sesekethe, ngokuphambene newashi (isiqondiso esifanayo neminwe emine yesandla sokunene).
Uma i-southern pole yamagnet ingena bese iphuma futhi phezulu, ugesi ugeleza uye kwesobunxele sesekethe bese uye kwesokudla sesekethe ukuze inaliti ye-galvanometer iphendukele kwesobunxele bese iye kwesokudla.
Kodwa uma i-southern pole yamagnet ingena kwi-coil bese ima, ugesi ugeleza uye kwesobunxele sesekethe bese uyama ukuze inaliti ye-galvanometer iphendukele kwesobunxele bese ibuyela ku-zero.
Impendulo efanele ngu-D.
