| E13.0125Idemo yomthetho kaLenz |
| Iqukethe amakhonkco ama-2 esinyithi adityaniswe ngumqadi wealuminium, onokujikeleza ngokukhululekileyo kwisitendi sesinyithi iDi.8cm. Enye yeeringi ivaliweyo; enye yenzelwe ukuthelekisa. Xa umazibuthe webar ungena ungene okanye uphume kwilogu ukutshintsha kwemagneti kuya kutshintsha. Ngokomthetho kaLenz, okwangoku kuya kubangelwa kwilogo yokuchasa utshintsho. Abafundi bangawuqinisekisa umthetho ngokuhlalutya ukuhamba kweluphu. |
