A na-ekewa inductance mgbanaka magnetik ka ọ bụrụ mgbanaka manganese-zinc ferrite na mgbanaka nickel-zinc ferrite. Dabere na ihe eji eme ihe, ihe nkedo calcined dịkwa iche. Mgbanaka magnetik nickel-zinc ferrite bụ nke iron, nickel, na zinc oxides ma ọ bụ nnu, nke a na-eme ya site na teknụzụ seramiiki eletrọnịkị. Ihe mgbanaka magnetik manganese-zinc ferrite bụ ígwè, manganese, zinc oxides na nnu, a na-ejikwa teknụzụ seramiiki eletrọnịkị mee ya. Ha bụ otu ihe ahụ na ihe na usoro, naanị ihe dị iche bụ na ihe abụọ ahụ, manganese na nickel, dị iche. Ọ bụ ihe abụọ a dị iche iche nwere mmetụta dị iche iche na otu ngwaahịa. Ihe manganese-zinc nwere ikike ndọta dị elu, ebe nickel-zinc ferrite nwere ikike ndọta dị ala. Enwere ike iji manganese-zinc ferrite na ngwa ebe oge ọrụ dị ala karịa 5MHz. Nickel-zinc ferrite nwere ihe mgbochi dị elu ma enwere ike iji ya na ọnụọgụ ugboro nke 1MHz ruo ọtụtụ narị megahertz. Ewezuga ndị inductor ọnọdụ nkịtị, maka ngwa n'okpuru 70MHz, mgbochi nke ihe manganese-zinc na-eme ka ọ bụrụ nhọrọ kacha mma; maka ngwa sitere na 70MHz ruo ọtụtụ narị gigahertz, a na-atụ aro ihe nickel-zinc. A na-ejikarị Manganese-zinc ferrite bead eme ihe n'ogo nke kilohertz ruo megahertz. Nwere ike ime inductors, transformers, cores filter, isi magnetik na mkpanaka antenna. Enwere ike iji mgbanaka magnetik nickel-zinc ferrite mee cores magnetik maka ndị na-agbanwe n'etiti etiti, isi magnetik, mkpara antenna na-efegharị mkpụmkpụ, ndị na-emegharị ihe inductance, na ihe ndọta saturation magnetik. Oke ngwa na ntozu ngwaahịa dị elu karịa mgbanaka magnetik ferrite Mn-Zn. Ọtụtụ. Mgbe a na-agwakọta cores abụọ ọnụ, kedu ka ị ga-esi mara ọdịiche dị n'etiti ha? A kọwara ụzọ abụọ akọwapụtara n'okpuru. 1. Usoro nlele anya: N'ihi na Mn-Zn ferrite na-enwekarị ikike dị elu, nnukwu ọka kristal, yana usoro dị ntakịrị, ọ na-abụkarị oji. Nickel-zinc ferrite n'ozuzu nwere obere permeability, ezigbo ọka, ihe owuwu na-agba agba, na-adịkarịkwa aja aja, karịsịa mgbe okpomọkụ dị ntakịrị n'oge usoro mmepụta. Dị ka àgwà ndị a si dị, anyị nwere ike iji ụzọ anya hụ ọdịiche. N'ebe na-egbuke egbuke, ọ bụrụ na agba nke ferrite dị oji ma nwee kristal na-egbuke egbuke, mgbe ahụ isi bụ manganese-zinc ferrite; ọ bụrụ na ị hụ na ferrite na-acha aja aja, ihe na-egbuke egbuke na-acha odo odo, na ihe ndị ahụ adịghị adọrọ adọrọ, Igwe magnetik bụ nickel-zinc ferrite. Usoro a na-ahụ anya bụ usoro siri ike, nke nwere ike ịmụta mgbe emechara ya. Usoro inductance mgbanaka magnetik 2. Usoro ule: Usoro a bụ nke a pụrụ ịdabere na ya, ma ọ chọrọ ụfọdụ ngwá ọrụ ule, dị ka mita nguzogide dị elu, mita Q mita dị elu, wdg 3. Nnwale nrụgide.
