Qaamuuska Erayada Magnet

Anisotropic(oriented) - Maaddadu waxay leedahay jihada la doorbido ee jihada birta.

Xoog lagu muquuniyo- Xoogga demagnetizing, oo lagu qiyaaso Oersted, lagama maarmaanka u ah in la yareeyo soo-gelinta la arkay, B ilaa eber ka dib markii magnet-ka hore loo keenay saturation.

Heerkulka Curie- Heerkulka kaas oo isbarbar-dhigga daqiiqadaha magnetic-ka hoose uu si buuxda u baaba'ayo, oo alaabtu ma sii hayn karto magnetization.

Gauss- Cutubka cabbirka kicinta magnetic, B, ama cufnaanta qulqulka ee nidaamka CGS.

Gaussmeter- Qalab loo isticmaalo in lagu cabbiro qiimaha degdegga ah ee bini'aadantinimada, B.
Flux Xaaladda ka jirta meel dhexe oo lagu sakhiray xoog birlabaysan. Tiradan waxaa lagu gartaa xaqiiqda ah in xoogga korantada lagu kiciyo kirishbooyada ku hareeraysan qulqulka wakhti kasta qulqulka qulqulka ayaa isbeddelaya xajmiga. Unugga qulqulka ee nidaamka GCS waa Maxwell. Hal Maxwell wuxuu la mid yahay hal volt x sekan.

Induction- Qulqulka magnetic halkii unug ee qayb ka mid ah qaybta caadiga ah ee jihada qulqulka. Unugga kicinta waa Gauss ee nidaamka GCS.

Khasaare aan ka noqosho lahayn- Demagnetization qayb ka mid ah magnetka oo ay sababto beeraha dibadda ama arrimo kale. Khasaarahan waxa kaliya oo lagu soo kaban karaa dib-u-magnetization. Magnets waa la dejin karaa si looga hortago kala duwanaanshaha waxqabadka ee ay keento khasaare aan dib loo celin karin.

Xoogaga qasabka ah ee gudaha, Hci- Cabbiraadda xoogga leh ee awoodda maaddada ee ka hortagga is-dejinta.

Isotropic (aan ku jirin)- Maaddadu ma laha jihada la doorbidayo ee jihada magnetic, taas oo u oggolaanaysa magnetization jihada kasta.

Xoogga Magnetization- Xoogga magnetomotive halkii dhererka halbeeg kasta oo ka mid ah wareegga magnetka. Cutubka xoogga birlabeedka ayaa ku jira nidaamka GCS.

Wax soo saarka tamarta ugu badan(BH) ugu badnaan - Waxaa jira dhibic ka mid ah Loop-ka Hysteresis kaas oo badeecada xoogga magnetization H iyo induction B ay gaaraan ugu badnaan. Qiimaha ugu badan waxaa lagu magacaabaa Alaabta Tamarta ugu badan. Halkaa marka ay marayso, mugga alaabta magnetka ee loo baahan yahay in lagu sameeyo tamarta la siiyay hareeraheeda waa ugu yaraan. Halbeeggaan waxaa guud ahaan loo adeegsadaa in lagu qeexo sida ay "xoog" u tahay maaddadan magnet-ka joogtada ah. Unuggiisu waa Gauss Oersted. Hal MGOe macnaheedu waa 1,000,000 Gauss Oersted.

Dhexgelinta Magnetka- B -Flux halkii halbeeg ee qaybta caadiga ah ee jihada dariiqa magnetic. Lagu cabbiray gaaska.

Heerkulka shaqada ee ugu badan- Heerkulka ugu sarreeya ee soo-gaadhista ee magnet-ku uu dhaafi karo iyada oo aan la helin xasillooni-darro muddada-dheer ah ama isbeddel qaabdhismeedka.

Cirifka Waqooyi- Tiirka birlababka ah ee soo jiidanaya cirifka woqooyiga.

Ogaysiiyay, Oe- Unug ka mid ah xoogga magnetization ee nidaamka GCS. 1 Oersted wuxuu la mid yahay 79.58 A/m marka loo eego nidaamka SI.

Permeability, Soo-noqoshada- Celceliska jiirada wareegga xuubka yar.

Polymer-Bonding -Budada magnetic waxaa lagu qasaa matrix side polymer, sida epoxy. Magnet-yadu waxay u samaysan yihiin qaab gaar ah, marka sidaha la adkeeyo.

Soo Bandhigista Hadhaaga,Br -Flux cufnaanta - Waxaa lagu cabbiraa gauss, oo ah walxo birlab ah ka dib markii si buuxda loogu dhejiyay wareeg xiran.

Magnets Dhulka Naadirka ah -Magnets ka samaysan walxo leh nambar atomic ah 57 ilaa 71 lagu daray 21 iyo 39. Waxay kala yihiin lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, yttrium.

Remanance, Bd- Induction-ka magnetic kaas oo ku sii jira wareegga birlabeedka ka dib marka laga saaro xoogga birlabeedka. Haddii uu jiro faraqa hawo ee wareegga, dib-u-celinta waxay ka yaraan doontaa soo-gelinta haraaga, Br.

Heerkulka isku-bedelka ah- Cabbirka isbeddellada dib-u-celinta ee qulqulka ee ay keento kala duwanaanta heerkulka.

Soo Gelitaanka Hadhaaga -Br Qiimaha kicinta ee barta Hysteresis Loop, kaas oo loop-ka Hysteresis ka gudbayo dhidibka B isagoo eber ah xoogga magnetizing. Br waxa uu ka dhigan yahay wax soo saarka cufnaanta birlabeed ee ugu badan ee walaxdan iyada oo aan lahayn goob birlabeedka dibadeed.

Saturation– Xaalad ay ka mid tahay induction offerromagneticmaaddadu waxay gaartay qiimihiisii ​​ugu badnaa iyadoo kororka xoogga magnetization-ka ee la dabaqay. Dhammaan daqiiqadihii magnetic-ka hoose waxay noqdeen kuwo u janjeedha hal jiha marka la joogo heerka saturation.

Sintering- Isku-xidhka budada isafgaradka iyadoo la adeegsanayo kuleyl si ay u suurtageliso mid ama in ka badan oo ka mid ah dhowr habab oo dhaqdhaqaaqa atomka ah ee isku dhafka xiriirka walxaha inay dhacaan; hababku waa: qulqulka viscous, dareeraha xalinta- roobaadka, fidinta dusha sare, faafidda bulk, iyo uumi- Uumi. Densification waa natiijada caadiga ah ee sintering.

Dahaarka dusha sare- Si ka duwan Samarium Cobalt, Alnico iyo alaabta dhoobada, kuwaas oo u adkaysta daxalka,Neodymium Iron Boronmagnets waxay u nugul yihiin daxalka. Iyada oo ku saleysan codsiga magnetka, dahaarka soo socda ayaa la dooran karaa si loogu dabaqo dusha sare ee Neodymium Iron Magnets - Zinc ama Nickel.
