The guryaha magnetic ah waxyaabaha la

Marka la geeyaa beer magnetic of shay, ay "dhaqanka" iyo nooca isbedel dhismaha guriga ku xirnaan doontaa wax ka shayga la sameeyo. Dhammaan qalabka loo yaqaan waxa loo qaybin karaa shan kooxood oo waaweyn: paramagnetic, ferromagnetic iyo antiferromagnetic, ferrimagnetic iyo diamagnetic. Sida laga soo xigtay soocidda this, guryaha kala duwan magnetic ah waxyaabaha la. Si aad u ogaato waxa qarsoon waxaa ka danbeeya ereyadan, ka fiirso koox kasta si faahfaahsan.

Muqaadaraadka soo bandhigista sifooyinka paramagnetism, permeability magnetic lagu gartaa calaamada wanaagsan, iyadoo aan loo eegin qiimaha duurka dibadda magnetic taas oo wax ka jarto. The wakiillo wanaagsan ee loo yaqaan kooxdan waa xabagta nitric iyo gaaska ogsijiin, xumadoodu-dhulka iyo kooxaha xumadoodu iyo cusbo ferrous.

The sumadda wanaagsan nuglaato magnetic sare (1 gaadho Mill.) Ferromagnets soo jireenka ah. In ku xiran xoogga duurka dibadda iyo nuglaato heerkulka si weyn loo kala duwan yahay. Muhiimsan, tan iyo daqiiqado of Qurub hoose waa sublattices kala duwan ee qaab-dhismeedka, qiimaha guud ee xilligan waa eber.

Sida horyaalka, iyo qaar ka mid ah guryaha ay wax ku dhow inay ferromagnetic yihiin. Waxay ka mideysan yihiin by tiirsanaanta sare ee nuglaato ee kulaylka iyo xoog duurka jooga, laakiin waxaa jira kala duwanaan. The daqiiqado magnetic meeleeyay atamka sublattices ma siman yihiin midba midka kale, si kastaba ha ahaatee, ka duwan kooxda hore, xilligan guud ahaan waa nonzero. Maandooriyaha soo jireenka ah ee magnetization ee lama filaan ah. Isgaarsiinta sublattices antiparallel. The ferrites wanaagsan ee loo yaqaan. guryaha magnetic xeryahooda of kooxdan yihiin sare, sidaa darteed waxay inta badan waxaa loo isticmaalaa in farshaxanka.

Oo xiiso gaar ah waa koox ka mid ah antiferromagnets. Marka qaboojinta, walxaha sida hoos ku atamka xadka heerkulka gaar ah iyo udhigo waxaa lagu abaabulaa dhismeedka daaqaddii crystal ah si dabiici ah u beddeli daqiiqado ay magnetic, isuna orientation protivoparallelnoe. nidaamka A gebi ahaanba kala duwan ka dhici by walxaha kulaylinta - uu duubay guryaha magnetic caan ku for koox ka mid ah walxaha paramagnetic. Tusaale ahaan waxaa ka mid ah carbonates, oxides, iyo si bixi.

Ugu dambayntiina, diamagnetic ah. The guryaha magnetic of walxaha kooxdan ha ku xiran tahay xoojinta berrinka, iyo qiimaha a of nuglaato magnetic waa negative. Haddii walax leeyahay bond covalent ah, waa diamagnetic "daahir ah". Wakiilada - dahab, copper, gaasas inert iyo si bixi.

The guryaha magnetic of maaddadu ay hubkaas ayaa loo isticmaalaa qalab casri ah. Tusaale ahaan, ka windings windings transformer dhaawacaa on qalabka magnetic jilicsan. High permeability iyo magnetized in robab, xataa xoogga yar yahay, macnaheedu cidhiidhi loop hysteresis ee garaafka, iyo sidoo kale khasaaraha yar ee dib u noqoshada magnetic sheegtay in injineernimada korontada. Haddii guryaha magnetic of arrinta u dhigma wax ka jilicsan magnetic, alaabooyinka waxaa lagu gartaa socodka weyn oo ka dhigay in la koobnayn oo kaliya markii ay heleen robab. In tababar, taas micnaheeda tahay in la yareeyo xajmiga Bannaanka magnetic, isla markaana hoos miisaanka qalab ah. Si kastaba ha ahaatee, faa'iidooyinka iyo khasaaro been - beerta talantaalli abuuraa hadda Eddy wax sida keenaya kulaylinta, si xal culays kaari ah.

nooc kale ee wax - adag xoog iyo qasab magnetic taas oo ah ugu yaraan 4000 amperes halkii mitir. Taas macnaheedu waa in ay beeraha magnetic of xoogga sare, ka dib markii taas oo wax ka xajisto guryaha magnetic, noqoto lagama maarmaanka u ah dib u noqoshada magnetization ah magnet joogto ah.
