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.

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.
