Nooc ka mid ah xoogga birlabeedka leh magnetism xooggan

Noocyada magnetic eeMagnets aad u xoog badan: Maqnaanshaha goob magnet ah oo dibadda ah, sababtoo ah is-dhaafsiga elektaroonigga ama isdhexgalka kale ee u dhexeeya atamka ku xiga ee goobta magnetic, daqiiqadahooda magnetic waxay ka gudbaan saameynta dhaqdhaqaaqa kuleylka, magnets xooggan ayaa ku jira nidaam qayb ahaan la joojiyay, taasoo keentay ifafaale. daqiiqad magnetic.Marka goob birlabeedka dibadda ah lagu codsado, magnetization-keedu wuxuu isku beddelaa goobta birlabeedka dibadda oo la mid ah kan walxaha ferromagnetic.Ferromagnetism iyo antiferromagnetism waxay leeyihiin dabeecad jireed oo isku mid ah, laakiin daqiiqadaha magnetic-ka ee isbarbar-dhigga ee feromagnets way kala weyn yihiin, sidaa darteed waxaa jira qayb ka mid ah daqiiqad birlab ah oo kedis ah, oo la mid ah feromagnet.Ferrites inta badan waa feromagnets.

Diamagnetism waa marka daqiiqadaha magnetic electrons ee atamka walaxda ay baabi'iyaan midba midka kale oo xilliga magnetka la isku daray uu yahay eber.Laakiin markaMagnets Dhulka Naadirka ah ee Xooganwaxaa lagu sakhiray goobta magnetic dibadda, dhaqdhaqaaqa orbital elektarooniga ah ayaa isbeddeli doona, oo soo saari doona daqiiqad yar oo birlab ah oo wadajir ah oo ka soo horjeeda goobta magnetic dibadda.Magnet xoog leh ayaa markaa u taagan sifooyinka birlabeed ee walaxda nuglaantana waxay noqotaa tiro taban oo aad u yar.U nuglaanshaha birlabku waa saamiga daqiiqada magnetic ee walaxda hoosteeda dhul magnetic dibadda ah (oo loo yaqaan magnetization) xoogga goobta magnetic, oo leh calaamadda κ.U nuglaanshaha walxaha guud ee antimagnetic waxay ku saabsan tahay in laga jaray hal qayb halkii milyan (-10-6).

U nuglaanshaha magnetic ee paramagnetism waa mid togan, 1 ~ 3 cabbir ka weyn diamagnetism, X waa qiyaastii 10-5 ~ 10-3, u hoggaansanaanta sharciga Curie ama sharciga Curie-Weiss.Marka ay jiraan ion, atamka ama molecules oo aan lahayn lammaane elektaroonig ah oo ku jira aMagnet Joogta ah ee Xoogan, waxaa jira xawaare xagal-xagalka ah iyo orbital angular of electrons, sidaas darteed waxaa jira daqiiqado magnetic ah iyo daqiiqado magnetic orbital.Marka la eego goobta birlabeedka dibadda ah, daqiiqadda magnetic-ka ee asalka ah ee khalkhalsan ayaa noqon doonta mid jihaysan, taas oo muujinaysa paramagnetism.
