Nkọwa okwu nke Magnet

Anisotropic(gbakwasara) - Ihe ahụ nwere ntụzịaka nke nghazi magnetik.

Ike mmanye- Ike demagnetizing, nke a tụrụ na Oersted, dị mkpa iji belata ntinye ahụrụ anya, B ruo efu mgbe ebubatala ndọta na saturation.

Curie okpomọkụ- Ọnọdụ okpomọkụ nke nhazi oge ndọta nke elementrị na-apụ n'anya kpamkpam, na ihe ndị ahụ enweghịzi ike ijide magnetization.

Gauss- Otu nha nke induction magnetik, B, ma ọ bụ njupụta njupụta na sistemụ CGS.

Gaussmeter- Ngwa eji elele uru ndọta ozugbo, B.
Flux Ọnọdụ dị n'ime igwe etinyere n'ike ndọta. A na-eji ọnụ ọgụgụ a mara site n'eziokwu ahụ bụ na a na-ebute ike electromotive n'ime onye na-eduzi gburugburu flux n'oge ọ bụla mgbanwe mgbanwe na-agbanwe n'ịdị ukwuu. Akụkụ nke mgbanwe na sistemụ GCS bụ Maxwell. Otu Maxwell hà nhata otu volt x sekọnd.

Ntinye- Igwe ndọta n'otu mpaghara nke ngalaba na-adaba na ntụzịaka nke ikuku. Ngalaba ntinye bụ Gauss na sistemụ GCS.

Mfu na-apụghị ịgbagha agbagha- Demagnetization akụkụ nke magnet kpatara site na mpaghara mpụga ma ọ bụ ihe ndị ọzọ. A na-enwetaghachi naanị mfu ndị a site na ndọta ọzọ. Enwere ike ime ka magnetik guzosie ike iji gbochie mgbanwe dị iche iche nke arụmọrụ sitere na mfu na-enweghị atụ.

Ike mmanye n'ime ime, Hci– Nleba anya nke ike ihe onwunwe nwere iguzogide nbibi onwe onye.

Isotropic (na-abụghị nke dabeere)- Ngwa ahụ enweghị ntụzi aka nke magnetik, nke na-enye ohere magnetization n'akụkụ ọ bụla.

Ike ndọta- Ike magnetomotive kwa otu ogologo n'oge ọ bụla na sekit magnetik. Akụkụ nke ike ndọta bụ Oersted na sistemụ GCS.

Ngwaahịa ike kacha(BH) max - Enwere ebe na Hysteresis Loop nke ngwaahịa magnetizing force H na induction B na-erute kacha. A na-akpọ uru kachasị elu ngwaahịa ike kacha. N'ebe a, olu ihe magnetik achọrọ iji wepụta ike enyere n'ime ya bụ opekempe. A na-ejikarị oke a kọwaa otu ihe ndọta a na-adịgide adịgide si “si ike”. Ngalaba ya bụ Gauss Oersted. Otu MGOe pụtara 1,000,000 Gauss Oersted.

Ntinye magnetik- B -Flux kwa mpaghara mpaghara nke akụkụ nke dabara na ntụziaka nke ụzọ magnetik. A tụrụ ya na gauss.

Okpomọkụ arụ ọrụ kacha- Okpomọkụ kachasị nke mkpughe nke magnet nwere ike ịhapụ na-enweghị nnukwu enweghị nnukwu ogologo ogologo ma ọ bụ mgbanwe nhazi.

Osisi North- Ogwe ndọta ahụ nke na-adọta mpaghara North Pole.

Ekele, oe- Otu akụkụ nke ike ndọta na sistemụ GCS. 1 Oersted nhata 79.58 A/m na sistemụ SI.

Permeability, mgbake– Nkezi mkpọda nke obere hysteresis loop.

Polymer-njikọ -A na-agwakọta ntụ ntụ magnetik na matriks na-ebu polymer, dị ka epoxy. A na-emepụta ihe ndọta n'ụdị ụfọdụ, mgbe a na-eme ka onye na-ebu ya sie ike.

Ntinye ihe fọdụrụ,Br -Flux njupụta - A tụrụ na gauss, nke ihe ndọta mgbe emechara ya nke ọma na sekit mechiri emechi.

Igwe Igwe Ọdụdọ Ụwa Na-adịghị ahụkebe -Igwe ndọta mere nke ihe nwere nọmba atọm site na 57 ruo 71 gbakwunyere 21 na 39. Ha bụ lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, na scandium, yttrium.

Remanance, Bd- Ihe ndọta ndọta nke na-anọgide na sekit magnetik mgbe ewepụsịrị ike magnetizing etinyere. Ọ bụrụ na enwere oghere ikuku na sekit, ncheta ahụ ga-adị obere karịa ntinye mpụta, Br.

Ọnụego ngbanwe okpomọkụ- Ntụle nke mgbanwe mgbanwe mgbanwe na mgbanwe okpomọkụ kpatara.

Ntinye ihe fọdụrụ -Br A uru nke ntinye n'ebe dị na Hysteresis Loop, ebe Hysteresis loop na-agafe axis B na efu magnetizing ike. Br na-anọchi anya nsonaazụ njupụta magnetik kachasị nke ihe a na-enweghị oghere magnetik mpụga.

Saturation– A ọnọdụ n'okpuru nke induction nkeferromagneticihe ruru oke uru ya na mmụba nke ike magnetizing etinyere. Oge ndọta niile agbakwasara ụkwụ n'otu ụzọ na ọkwa saturation.

Na-egwu egwu– The bonding nke ntụ ntụ compacts site ngwa nke okpomọkụ na-enyere otu ma ọ bụ karịa nke ọtụtụ usoro nke atọm ije n'ime urughuru kọntaktị interfaces ime; usoro ndị a bụ: viscous eruba, mmiri mmiri na-adọ ngwọta-mmiri mmiri, elu mgbasa, nnukwu mgbasa, na evaporation-condensation. Densification bụ ihe a na-emekarị site n'ịgbagharị.

Mkpuchi elu- N'adịghị ka Samarium Cobalt, Alnico na seramiiki ihe, nke na-eguzogide corrosion,Neodymium Iron boronihe ndọta na-enwe ike imebi. Dabere na ngwa ndọta, enwere ike ịhọrọ mkpuchi na-esote ka ọ tinye n'elu Neodymium Iron Boron magnet - Zinc ma ọ bụ Nickel.
