Uluhlu lwemigaqo yeMagnet
Anisotropic(ijolise) - Izinto eziphathekayo zinendlela ekhethiweyo yokuqhelaniswa nemagnethi.
Amandla okunyanzela- Amandla okuphelisa uzibuthe, alinganiswe e-Oersted, ayimfuneko ekunciphiseni ukwenziwa okujongiwe, B ukuya kwiqanda emva kokuba umazibuthe sele eziswe kwi-saturation.
Ubushushu beCurie-Iqondo lobushushu apho ulungelelwaniso oluhambelanayo lwamaxesha emagnethi lunyamalala ngokupheleleyo, kwaye izixhobo azisakwazi ukubamba imagneti.
Gauss-Iyunithi yomlinganiselo wokungeniswa kwamagnetic, B, okanye ukuxinana kweflux kwinkqubo yeCGS.
I-Gaussmeter-Isixhobo esisetyenziselwa ukulinganisa ixabiso elikhawulezileyo lokungeniswa kwemagnethi, B.
I-Flux Imeko ekhoyo kwindawo ephantsi kwamandla amagnetizing. Lo buninzi bubonakaliswa yinto yokuba amandla e-electromotive anyanzeliswa kwi-conductor ejikeleze i-flux nangaliphi na ixesha utshintsho oluguqukayo kubukhulu. Iyunithi yokuguquguquka kwinkqubo ye-GCS nguMaxwell. Omnye uMaxwell ulingana ne volt enye x imizuzwana.
Ukungeniswa– Umbane wemagnethi kwindawo yeyunithi yecandelo eliqhelekileyo ukuya kwicala lokuhamba. Iyunithi yoqheliso yiGauss kwinkqubo yeGCS.
Ilahleko engenakubuyiseka-Inxalenye yemagnethi yemagnethi ebangelwa ngamasimi angaphandle okanye ezinye izinto. Ezi lahleko zifumaneka kuphela ngokuphinda kusebenze uzibuthe. Iimagnethi zinokuzinziswa ukunqanda ukuguquguquka kokusebenza okubangelwa yilahleko engenakubuyiselwa.
I-Intrinsic Coercive Force, Hci-Oersted umlinganiselo wesakhono sendalo sokumelana ne-self-demagnetization.
Isotropic (engaqhelananga)-Izinto eziphathekayo azikho icala elikhethiweyo lokuqhelaniswa nemagnethi, evumela imagneti kulo naliphi na icala.
Amandla oMazibuthe– Amandla emagnetomotive ngobude beyunithi nakweyiphi na indawo kwisekethe yemagnethi. Iyunithi yamandla ombane i-Oersted kwinkqubo ye-GCS.
Ubuninzi beMveliso yaMandla(BH) max - Kukho inqaku kwi-Hysteresis Loop apho imveliso ye-magnetizing force H kunye ne-induction B ifikelela phezulu. Ixabiso eliphezulu libizwa ngokuba yiMveliso yaMandla aphezulu. Ngeli xesha, umthamo wezinto zikamagnethi ezifunekayo ukwenza iprojekthi yamandla anikiweyo kwindawo eyingqongileyo ubuncinci. Le parameter isetyenziswa ngokubanzi ukuchaza indlela "yomelele" ngayo le nto yemagnethi esisigxina. Iyunithi yayo yiGauss Oersted. I-MGOe enye ithetha i-1,000,000 ye-Gauss Oersted.
Ukungeniswa kweMagnetic– B -Flux kwindawo yeyunithi yecandelo eliqhelekileyo ukuya kwicala lendlela yamagnetic. Ilinganiswe nge-gauss.
Ubushushu obuphezulu bokusebenza-Obona bushushu buphezulu bokuvezwa ukuba umazibuthe unokuhamba ngaphambili ngaphandle kokungazinzi kuluhlu olude okanye utshintsho kulwakhiwo.
ipali yasemantla– Laa pali kazibuthe etsala igeographical North Pole.
Ewe, Oe-Iyunithi yamandla ombane kwinkqubo ye-GCS. I-1 i-Oersted ilingana ne-79.58 A/m kwinkqubo ye-SI.
Ukunyanzeliswa, ukuyekelela– I-Avareji yokuthambeka kwe-hysteresis loop encinci.
I-Polymer-Bonding -Umgubo wemagnethi uxutywe kunye ne-polymer carrier matrix, efana ne-epoxy. Iimagnethi zenziwe ngendlela ethile, xa umthwali eqinile.
Ukungeniswa okushiyekileyo,Ubuninzi be-Br -Flux-Ilinganiswe kwi-gauss, ye-magnetic material emva kokuba i-magnetized ngokupheleleyo kwisekethe evaliweyo.
Iimagnethi zomhlaba ezinqabileyo -Iimagnethi ezenziwe ngezinto ezinenombolo ye-athomu ukusuka ku-57 ukuya ku-71 kunye no-21 kunye no-39. Ziyilanthanum, i-cerium, i-praseodymium, i-neodymium, i-samarium, i-europium, i-gadolinium, i-terbium, i-dysprosium, i-holmium, i-erbium, i-thulium, i-ytterbium, i-scantium, i-lute iyttrium.
Remanance, Bd-I-magnetic induction ehlala kwisekethe yamagnetic emva kokususwa kwamandla asetyenziswayo. Ukuba kukho i-gap yomoya kwisekethe, i-remenance iya kuba ngaphantsi kwe-residual induction, i-Br.
I-Coefficient yoBubushushu obubuyiselwa umva– Umlinganiselo wokutshintsha okuguquguqukayo okubangelwa kukuguquguquka kobushushu.
Ukungeniswa okushiyekileyo -Br Ixabiso le-induction kwindawo e-Hysteresis Loop, apho i-Hysteresis loop inqumla i-axis ye-B nge-zero magnetizing force. I-Br imele ubuninzi be-magnetic flux density output yale mathiriyeli ngaphandle kwendawo yangaphandle yamagnetic.
Ukwaneliseka– Imeko apho ukuqaliswa kwei-ferromagneticimathiriyeli ifikelele elona xabiso liphezulu ngokunyuka kwamandla emagnetizing asetyenziswayo. Onke amaxesha emagnethi aqala kwicala elinye kwimo yokuzalisa.
Sintering– Ukudityaniswa komgubo oxubeneyo ngokusetyenziswa kobushushu ukwenzela ukuba enye okanye ngaphezulu kweendlela ezininzi zokushukuma kwe-athomu kunxibelelwano lwamasuntswana onxibelelwano lwenzeka; Iindlela zezi: ukuhamba kwe-viscous, inqanaba lolwelo lwesisombululo-imvula, ukusasazwa komphezulu, ukusasazwa kwesambuku, kunye ne-evaporation-condensation. Uxinaniso sisiphumo esiqhelekileyo se-sintering.
Iingubo zoMphezulu- Ngokungafaniyo neSamarium Cobalt, iAlnico kunye nezixhobo ze-ceramic, ezinganyangekiyo kwi-corrosion,Neodymium Iron Boroniimagnethi zisengozini yokubola. Ngokusekwe kwisicelo semagnethi, kukhethwe ukwambathisa okulandelayo ukuze kufakwe kumphezulu weNeodymium Iron Boron umazibuthe-Zinc okanye iNickel.
