A shugaba layi da kuma filin

Idan uncharged karfe samfurin sanya shi a cikin wani lantarki filin, akwai taso wani umurni da directional yunkuri na free cajin yan dako, aka fi sani a matsayin halin yanzu. A vector filin Lines da kuma na yanzu kwatance ne m. A karafa, da watsin ne saboda da motsi na electrons. Tun da samfurin ne ba wani ɓangare na rufaffiyar kewaye da shi a karkashin mataki na filin zai zama redistribution na free cajin yan dako a hannu daya don tara da electrons kafa wani mummunan m, da kuma sauran an kafa na aibi, Ina nufin wani m alama. Wannan sabon abu ne ya sa ta rinjayar wani waje lantarki filin, da ake kira "shigar da". Zaka kuma iya ce cewa electrostatic shigar da - a sabon abu na redistribution na cajin yan dako jawo by wani lantarki filin. Ya kamata a lura cewa tasiri a kan shugaba da kuma ciwon Magnetic filin. Saboda haka, juyi na Magnetic shigar da na iya shiga cikin conductive abu halitta wani jawo halin yanzu a cikinta. Har ila yau, a sakamakon da summation magnetization inducing abu da waje filin da ciki filin tasowa. Kalmar "kammala shigar da" kawai koma zuwa wannan adadin.
