Ingcaciso: Izikrufu zefanitshala kunye namandongomane luhlobo lwesivalo esisetyenziselwa ukwenza unxibelelwano ngomatshini phakathi kwezinto zokutshatisa. Zisetyenziswa kakhulu kwimveliso yezeMveliso, kubomi bemihla ngemihla, njl.
Ezi zinokuchasana kakuhle neekhemikhali kwaye zinokuba nemagneti kancinci. Ubude bulinganiswa busuka phantsi kwentloko. Tshatisa umsantsa wokuqhekeka kwezinto zokudibanisa. Imisonto erhabaxa ngumgangatho womzi mveliso;
Imisonto entle kunye neyongezelelweyo-ethe-ethe yahlulwa ngokusondeleyo ukunqanda ukukhululeka kukungcangcazela; ukucoca umsonto, kokukhona ukuxhathisa.
Kukho lonke uhlobo lobungakanani kunye nokubalulwa esinokukunika, wamkelekile ukudibana.
