(1) Ọdịda electromagnet nha nha
N'ihi ịka nká, kọntaktị na-adịghị mma nke oghere wiring [base] nke mgbakọ plọg na ịgbado ọkụ nke ụzọ electromagnet, electromagnet nke nha enweghị ike ịrụ ọrụ (enweghị ike iburu ugbu a). N'oge a, enwere ike iji mita eletrik chọpụta, ọ bụrụ na achọpụtara nguzogide na-enweghị njedebe, ị nwere ike ịmegharị ụzọ ahụ, rụzie oghere ma gbanye oghere ahụ nke ọma.
Ọdịda nke mgbakọ waya gụnyere ịka nká eriri igwe, ike ọgwụgwụ waya, mgbaji waya dị n'ime yana ịrị elu oke ikuku
Ihe omume. Mkpokọta okpomọkụ ịrị elu dị ukwuu iji mee ka mmepụta ike nke electromagnet nha anya ezughi oke, ndị ọzọ ga-eme ka electromagnet nha anya enweghị ike ịrụ ọrụ.
