Ntuziaka ndọta
Usoro nghazi nke ihe ndọta na usoro mmepụta bụ magnet anisotropic.A na-akpụzi magnetik na ntụgharị ndọta, yabụ, ọ dị mkpa iji chọpụta ntụzịaka nghazi tupu mmepụta, ya bụ ntụzịaka magnetization nke ngwaahịa.
Tinye ihe ndọta ahụ na ndọta na-adịgide adịgide yana ntụzịaka nke mgbaka ndọta, wee jiri nwayọ na-abawanye ike ndọta iji ruo steeti saturation teknụzụ, nke a na-akpọ magnetization.Magnet n'ozuzu nwere square, cylinder, mgbanaka, tile, ekara na ụdị ndị ọzọ.Ntụziaka magnetization anyị na-ahụkarị nwere ụdị ndị a, enwere ike ịhazi pụrụ iche dịka ihe ndị ahịa chọrọ.
