Curie okpomọkụ nke isi ihe ngbanwe

"Oge ụfọdụ laa azụ, mmadụ jụrụ ma magnetik core nwere ọkwa na-eguzogide okpomọkụ. Ma onye zara ya otu a:

'Ọkwa nguzogide okpomọkụ bụ maka ihe mkpuchi. A naghị ewere isi magnetik dị ka ihe mkpuchi, yabụ na ọ nweghị ọkwa nguzogide okpomọkụ. Mana ọ nwere oke okpomọkụ metụtara ọnọdụ okpomọkụ akpọrọCurie okpomọkụ.'

Taa, ka anyị kparịta maka 'Curie okpomọkụ' nke magnetik isi.

Okpomọkụ Curie, nke a makwaara dị ka ebe Curie ma ọ bụ ebe mgbanwe magnetik, bụ mgbe ike ndọta nke ihe ahụ dara na 0 ka ọ na-ekpo ọkụ. Ndị Curies chọtara ya na njedebe narị afọ nke 19: mgbe ị na-ekpo ọkụ magnet n'otu okpomọkụ, magnetism mbụ ya na-apụ n'anya.

Na transformers (inductors), ọ bụrụ naisi magnetik's okpomọkụ na-aga n'elu Curie okpomọkụ, ọ nwere ike ime ka inductance na-adaba na 0. Ọ bụ ezie na ọtụtụ ngwaahịa nwere ike nwetaghachi ọrụ ha mgbe ọ jụrụ oyi, n'ihi na ndị na-agbanwe agbanwe (inductor) na-arụ ọrụ, inwe inductance efu ga-eduga na ọdịda na ike ọgwụgwụ.

Ya mere, mgbe ị na-emepụta na ịhọrọihe ntụgharị(inductors), ọ dị mkpa ịhapụ akụkụ ụfọdụ maka idobe okpomoku magnetik n'okpuru ebe Curie ya n'oge arụ ọrụ.

Okpomọkụ Curie nke ike manganese-zinc ferrite karịrị 210 Celsius. Ọtụtụ ihe mkpuchi ihe mkpuchi (inductor) nwere okpomọkụ dị ala karịa nke a, yabụ n'oge a na-arụ ọrụ, ihe ndọta n'ozuzu agaghị eru oke okpomọkụ dị otú ahụ.

Okpomọkụ Curie nke manganese-zinc ferrite nwere mmetụta dị elu karịrị 110 Celsius. Ọtụtụ ihe mkpuchi ihe mkpuchi (inductor) nwere ike ijikwa okpomọkụ dị elu karịa nke a, na okpomọkụ nke transformer (inductor) mgbe ọ rụchara ọrụ nwere ike ịdị mfe karịa nke a. Ya mere, anyị kwesịrị n'ezie ịṅa ntị na otú anyị na-emepụta elu-conductivity magnetik cores iji jide n'aka na ha anaghị adị oke ọkụ mgbe ha na-eji.

Okpomọkụ Curie nke nickel-zinc ferrite karịrị 100 Celsius. Dị nnọọ ka ọ dị elu-conductivity ferrite, ọ dị oke mkpa ijide n'aka na magnetik core anaghị adị ọkụ karịa Curie okpomọkụ mgbe transformer (inductor) na-arụ ọrụ. Nke a dị oke mkpa maka ngwaahịa nickel-zinc anyị na-ejikarị, dị ka inductors nwere ụdị m, inductor nwere ụdị mkpanaka, na nickel-zinc toroidal inductor.

The Curie okpomọkụ nke alloy powder core karịrị 450 ℃, nke mara mma elu. N'okwu a, anyị ga-akpachapụ anya maka otu ihe ndị ọzọ nke transformer (inductor) nwere ike isi jikwaa okpomọkụ.
