Taw qhia rau Magnet terminology

Sib nqus hlau nplaum - xaiv cov kev taw qhia uas yooj yim rau hlau nplaum raws li kev taw qhia.

Tib-Sex Magnets - Cov khoom sib nqus yog tib yam hauv txhua qhov kev taw qhia.

Coercive force Hcb —— txhawm rau txo B ntawm cov hlau nplaum ruaj khov mus rau kev saturation rau xoom, thiab lub zog ntawm qhov rov qab sib nqus teb yuav tsum tau ntxiv.

Temperature Coefficient - Qhov kub ntawm cov hlau nplaum poob nws cov khoom sib nqus

Sib nqus flux - lub cev kom muaj nuj nqis sawv cev rau kev faib tawm ntawm cov hlau nplaum, chav tsev yog Weber

Gauss - Sib nqus flux kab ib square centimeter, ib qho kev ntsuas ntawm magnetic flux ceev

Induction intensity B - lub cev kom muaj nuj nqis piav txog lub zog thiab kev taw qhia ntawm cov hlau nplaum, ntsuas nrog Gauss meter.

Intrinsic coercive force yog ib qho kev ntsuas siv los ntsuas qhov muaj peev xwm tiv thaiv demagnetization ntawm cov hlau nplaum, thiab chav tsev yog Oersted.

Irreversible poob - ib nrab demagnetization tshwm sim los ntawm lwm yam

Magnetic Field Strength - Lub zog sib nqus ntsuas ntawm qhov tseeb.

Magnetic Flux - Tag nrho cov hlau nplaum induction nyob rau hauv ib cheeb tsam.

Magnetic force - lub zog magnetomotive ib chav tsev ntev ntawm txhua qhov chaw ntawm lub zog sib nqus.

Magnetomotive muaj peev xwm - Qhov sib txawv ntawm magnetic vector muaj peev xwm ntawm ob lub ntsiab lus.

Maxwell - chav tsev ntawm magnetic flux, ib Maxwell yog cov hlau nplaum ntawm ib kab.

Oersted - Ib chav tsev ntawm magnetic teb lub zog los yog lub zog.

Magnetization Direction - Cov kev taw qhia nyob rau hauv uas sib txawv poj niam txiv neej hlau nplaum yuav tsum tau magnetized rau optimum kev ua tau zoo.

Magnetization saturation - thaum lub magnetic flux ncav cuag ib tug npaum li cas thiab tsis tuaj yeem nce infinitely, nws tseem nyob ntawm ib qho nyiaj.

Stability - irreversible poob ntawm cov hlau nplaum yog hais txog me me, thiab stability yog ntau dua.

Qhov siab tshaj plaws magnetic zog khoom (BH) max - cov khoom ntawm B thiab H ntawm txhua qhov chaw ntawm lub demagnetization nkhaus, uas yog, Bm, Hm thiab (BH) sawv cev rau lub zog sib nqus sib nqus tsim los ntawm cov hlau nplaum hauv qhov chaw huab cua, uas yog, cov hlau nplaum zoo li qub rau ib chav tsev ntim ntawm cov pa sib txawv Zog, txij li lub zog no sib npaug rau cov khoom ntawm cov hlau nplaum Bm thiab Hm, nws yog hu ua cov khoom siv hluav taws xob sib nqus, thiab kev sib raug zoo nkhaus ntawm cov khoom sib nqus hluav taws xob hloov nrog B yog hu ua qhov sib nqus zog nkhaus, thiab cov khoom ntawm Bd thiab Hd sib raug rau ib qho taw tes muaj tus nqi siab tshaj plaws, uas yog hu ua qhov siab tshaj plaws Magnetic zog khoom.

Remanent magnetism Br - qhov sib nqus induction siv sab laug los ntawm cov hlau nplaum tom qab cov hlau nplaum yog hlau nplaum thiab cov hlau nplaum raug tshem tawm.

Gaussmeter - Ib qho cuab yeej siv los ntsuas qhov sib nqus induction.

Hysteresis voj-Nyob rau hauv lub magnetic teb, kev sib raug zoo ntawm magnetic induction siv thiab lub magnetic teb siv ntawm lub ferromagnet yuav sawv cev los ntawm ib tug nkhaus. Thaum lub magnetizing magnetic teb hloov ib ntus, kev sib raug zoo ntawm magnetic induction induction thiab magnetic teb siv nyob rau hauv lub ferromagnet yog ib tug kaw kab. Cov kab kaw no hu ua hysteresis voj.

Sib Nqus Ncej - Ib yam ntxwv ntawm qhov chaw tshwj xeeb ntawm cov hlau nplaum ruaj khov, qhov txawv ntawm North (N) thiab Sab Qab Teb (S).

Plating / Deg Txheej - Feem ntau NdFeB hlau nplaum yog plated los yog coated los tiv thaiv cov hlau nplaum los ntawm corrosion. Neodymium hlau nplaum feem ntau yog tsim los ntawm peb cov ntaub ntawv: neodymium, hlau thiab boron. Yog tias tsis muaj txheej txheej, cov hlau hauv cov hlau nplaum yuav xeb. Cov hlau nplaum feem ntau yog triple-plated npib tsib xee-tooj-nickel, zinc-plated, tab sis qee qhov yog kub-, nyiaj-, lossis dub-nickel-plated, thiab lwm tus yog neodymium hlau nplaum uas coated nrog epoxy, yas, lossis roj hmab.

Sib Nqus Flux Density - ib lub npe hu ua magnetic induction, uas qhia tias muaj pes tsawg lub magnetic teb kab dhau los ntawm ib cheeb tsam perpendicularly, thiab cov kab sib nqus flux feem ntau yog ntsuas hauv Gauss (CGS).
