Impendulo efanele ngu-D.

20. Uma u-q eyishaja kagesi elungile, u-v ukunyakaza kweshaja, u-B uyinsimu yamagnetic kanti u-F uyisiqondiso samandla kazibuthe, khona-ke isithombe esifanele seshaja ewela insimu yamagnetic…

Incazelo yezimpawu u-x no-o esithombeni
Bheka izithombe ezingenhla. Uphawu u-x lusho ukuthi indlela yensimu yamagnetic u-B iqonde ngaphakathi ngendiza yokuqapha (kude nomfundi). Uphawu u-o lusho ukuthi indlela yensimu yamagnetic u-B iqonde ngaphandle (ibheke kumfundi).

Isiqondiso sokunyakaza kweshaja kagesi (v), isiqondiso sensimu yamagnetic (B) kanye nesiqondiso samandla kazibuthe (F) ziqondene ngqo. Isiqondiso sokunyakaza kweshaja kagesi, insimu yamagnetic kanye namandla kazibuthe sinqunywa ngokunembile kusetshenziswa umthetho wesandla sokunene.

Umthetho wesandla sokunene
Yelula isandla sakho sokunene, qondisa isithupha sakho, bese uvala eminye iminwe yakho emine. Hlela iminwe yakho emine ukuze ikhombe ohlangothini lwensimu yamagnetic (B). dan Isithupha sibonisa indlela yokushaja (v). Uma ukushaja kukuhle, intende yesandla sokunene ikhomba amandla kazibuthe (F). Uma ukushaja kukubi, ingemuva lesandla sokunene likhomba amandla kazibuthe (F).

Sebenzisa umthetho wesandla sokunene ezithombeni ezingenhla.
Impendulo efanele ngu-A.
