Ntọala nke ịkụcha ihe

Isi nke induction chaa chaa a ghọtara ma tinye ya n'ọrụ n'ichepụta kemgbe 1920s. N'oge Agha Ụwa nke Abụọ, nkà na ụzụ mepụtara ngwa ngwa iji nweta ngwa ngwa ngwa ngwa ngwa ngwa maka usoro ngwa ngwa, nke a pụrụ ịdabere na ya iji rụọ ọrụ ígwè ígwè. N'oge na-adịbeghị anya, ilekwasị anya n'ichepụta usoro ịmepụta ihe na nrụgide maka njikwa mma akara mma edugala na rediscovery nke nkà na ụzụ mmepụta, yana mmepe nke a na-achịkwa, niile siri ike ntinye ike oku.

Igwe ọkụ na-ekpo ọkụ na-ewere ọnọdụ na ihe na-eduzi ihe (ọ bụchaghị ígwè magnet) mgbe a na-etinye ihe ahụ n'ọhịa dị iche iche. Mkpọ oku na-ekpo ọkụ bụ n'ihi hysteresis na losses ugbu a na-efu.

Hysteresis na-efu naanị na ihe ndị magnetik dịka nchara, nickel, na ndị ọzọ pere mpe. Hysteresis ọnwụ na-ekwu na nke a na-akpata esemokwu n'etiti ụmụ irighiri ihe mgbe magnetized ihe ahụ n'otu ụzọ, na nke ọzọ. Enwere ike iwere mkpụrụ ndụ ndị ahụ dị ka obere nju nke na-atụgharị na ntụgharị ihu ọ bụla nke mpaghara ndọta. A choro oru (ike) iji gbanwee ha. Ike na-agbanwe n'ime okpomọkụ. Ọnụego mmefu nke ume (ike) na-abawanye site na mmụba ụba nke mgbanwe (ugboro ole).

Eddy ugbu a na-efunahụ ihe ọ bụla na-eduzi ihe na mpaghara ndọta dịgasị iche. Nke a na - ebute isi, ọbụlagodi na akụrụngwa enweghị nke ọ bụla nwere ihe magnetik na - ejikọtakarị ya na igwe na igwe. Ihe atụ bụ ọla kọpa, ọla, aluminom, zirconium, nonmagnetic steel nchara, na uranium. Eddy na-ebili mmiri bụ mmiri eletrik na-ebute site na ọrụ ntụgharị na ihe. Dị ka aha ha na-egosi, ha na-apụta na-agagharị na swirls na eddies n'ime ihe siri ike. Eddy ugbu a dị ezigbo mkpa karịa hysteresis na ntinye ọkụ. Rịba ama na a na-etinye kpo oku n'ime ihe ndị na-abụghị nke na-arụ ọrụ, ebe ọnweghị ọnya hysteresis.

Maka kpo oku nke nchara maka ime ka ike, ịkpụ, agbaze, ma ọ bụ nzube ọ bụla nke chọrọ okpomọkụ karịa Curie okpomọkụ, anyị apụghị ịdabere na hysteresis. Akụrụ na-efunahụ ihe ndị magnet ya dị elu karịa okpomọkụ a. Mgbe ígwè dị ọkụ n'okpuru ebe Curie, onyinye nke hysteresis na-adịkarị obere nke na enwere ike ileghara ya anya. Maka nzube niile ọ bụla, m2R nke agba mmiri ediri bụ naanị ụzọ nke ike ọkụ eletrik nwere ike isi ghọọ okpomọkụ maka ịmepụta ihe ọkụ ọkụ.

Ihe abụọ dị mkpa maka ịmepụta ọkụ na-eme:

  • A na-agbanwe usoro magnet
  • Ihe na-eduzi ihe na-emepụta ihe ọkụkụ na-etinye n'ime oghere magnet
