(Ntụgharị Demagnetization maka N40UH Neodymium Magnet)
Magnet adọrọwo mmasị ụmụ mmadụ ruo ọtụtụ narị afọ, na-egosipụta ike ndị na-adọrọ adọrọ ndị yiri ihe a na-apụghị ịkọwa akọwa. N'ime obi ike ndọta dị n'usoro demagnetization, echiche bụ isi n'ịghọta njirimara magnetik ya. Na blọgụ blọgụ a, anyị na-abanye na njem iji demystify demystification curve demagnetization, na-ekpughe ihe nzuzo dị n'azụ iwu ya na mkpa ọ dị na ngwa dị iche iche. Yabụ, ka anyị banye n'ime ụwa nke magnetism wee chọpụta ihe a na-atọ ụtọ!
Demagnetization curve ekwuputala
Ọkpụkpụ demagnetization, nke a makwaara dị ka usoro ndọta ma ọ bụ loop hysteresis, na-egosipụta omume nke ihe ndọta mgbe edobere ya na mpaghara ndọta na-agbanwe agbanwe. Ọ na-egosi njikọ dị n'etiti ike nke ebe ndọta na ihe ndọta magnetik na-ebute ma ọ bụ njupụta njupụta. Site n'ichepụta ike magnetik (H) na x-axis na magnetik flux density (B) na y-axis, demagnetization curves na-enye anyị ohere ịghọta na nyochaa njirimara magnetik nke ihe.
Ịghọta Omume nke Ngwa Igwe Ọdụdọ
Site n'ile anya n'akụkụ akụkụ nke demagnetization, anyị nwere ike ịchọpụta isi ihe na-akọwapụta omume ihe n'ime oghere magnetik dị iche iche. Ka anyị nyochaa akụkụ atọ dị mkpa:
1. Saturation point: Na mbụ, usoro ahụ na-arị elu nke ọma ruo mgbe ọ ruru n'ókè, ebe ọ dịghị mmụba na ike magnetik ga-emetụta njupụta njupụta. Isi ihe a na-egosi saturation nke ihe. Ihe dị iche iche nwere isi saturation dị iche iche, nke na-anọchite anya ikike ha ịnọgide na-enwe magnetik n'okpuru ebe ndọta siri ike.
2. Mmakọ: N'ịga n'ihu n'akụkụ akụkụ ahụ, ike ndọta na-ebelata, na-ebute mbelata nke njupụta magnetik. Otú ọ dị, mgbe ihe ahụ na-ejigide ụfọdụ n'ókè nke magnetization, a ga-enwe ebe ebe mgbanaka na-ejikọta x-axis. Njikọta a na-anọchi anya ike mmanye, ma ọ bụ ike mmanye, nke na-egosi ihe na-eguzogide demagnetization. A na-eji ihe ndị nwere mmanye dị elu mee ihe na ndọta na-adịgide adịgide ma ọ bụ ngwa ndọta ndị ọzọ na-adịgide adịgide.
3. Remanence: Mgbe ike ndọta erute efu, usoro ahụ na-ejikọta y-axis iji nye njupụta ma ọ bụ remanence flux. Oke a na-egosi ogo nke ihe ahụ na-anọgide na magnetik ọbụlagodi mgbe ewepụrụ oghere ndọta dị n'èzí. Ọdịda dị elu dị oke mkpa maka ngwa chọrọ omume magnetik na-adịte aka.
Ngwa na mkpa
Ntugharị demagnetization na-enye nghọta bara uru na nhọrọ ihe na njikarịcha maka ngwa dị iche iche. Nke a bụ ọmụmaatụ ụfọdụ dị mkpa:
1. Motors: Ịmara demagnetization usoro na-enyere aka n'ichepụta ịrụ ọrụ nke ọma Motors na kachasị magnetik ihe nwere ike idi elu magnetik ubi enweghị demagnetization.
2. Nchekwa data magnetik: Demagnetization curves na-enyere ndị injinia aka ịmepụta mgbasa ozi ndekọ magnetik kachasị mma na mmanye zuru oke maka nchekwa data a pụrụ ịdabere na ya na nke na-adịgide adịgide.
3. Ngwaọrụ Electromagnetic: Ịmepụta cores inductor na transformers chọrọ nlebara anya nke ọma maka akụkụ demagnetization iji kwado ihe achọrọ ọkụ eletrik na igwe.
Mmechi
Banye n'ime ụwa nke magnets site na oghere nke demagnetization curves, na-ekpughe mgbagwoju anya nke omume ihe ndọta na ngwa ha. Site n'iji ike nke usoro a, ndị injinia na-emeghe ụzọ maka ọganihu ọhụrụ gafee mpaghara dịgasị iche iche, na-akpụzi ọdịdị nkà na ụzụ nke ọdịnihu. Ya mere, oge ọzọ ị ga-ahụ magnetik, wepụta oge iji ghọta sayensị dị n'azụ magnetism ya na ihe nzuzo zoro ezo n'ime usoro demagnetization dị mfe.
