A na-akpọ akụrụngwa a na-eji magnetization magnetizer, ma ọ bụ igwe magnetik.Magnetizer na-ebu ụzọ kwụọ capacitor na voltaji DC dị elu (ya bụ, na-echekwa ike), wee wepụta ya site na eriri igwe (magnetizing fixture) na nguzogide dị ala.Ọnụ ọgụgụ kasị elu nke mpụta mgbapụta nwere ike ịdị oke elu, na-eru ọtụtụ iri puku amperes.Ụkụ a dị ugbu a na-emepụta oghere magnetik dị ike n'ime ihe nrụnye magneti, nke na-eme ka magnetik etinye n'ime ya kpamkpam.
Ihe mberede nwere ike ime n'oge usoro ndọta, dị ka saturation na-ezughị ezu, mgbawa nke mkpanaka magnetizer, na mgbaji nke magnet.
Saturation na-ezughị ezu bụ n'ihi voltaji chaja ezughị ezu, ebe oghere magnetik nke eriri igwe na-emepụta adịghị eru 1.5 ruo 2 ugboro saturation magnetization nke magnet.
