Magnetic zvigadzirwa zvinoshandiswa zvakanyanya muminda yakawanda, kusanganisira indasitiri, kurapwa, hupenyu hwepamba, zvemagetsi kutaurirana uye zvekufambisa. Vane kuvimbika kwepamusoro, magnetism yakagadzikana, kuchengetedza simba, kuchengetedza kwezvakatipoteredza, kuchengetedza kwakanaka uye kusimba. Ivo vanotsigira akasiyana magadzirirwo, angave akareruka maumbirwo ejometri kana maumbirwo akaomarara, anogona kugadzirwa pazvinodiwa, nekudaro achinyatso kuenderana neakasiyana mashandisirwo mamiriro.
