Erit High Temperature Demagnetize NdFeB Magnets

Rara terrae neodymium magnetum ferro-boron (NdFeB) magnetes permanentes potentissimi sunt et in variis applicationibus late usi sunt. Notae sunt propter altitudinem campi magnetici robur, stabilitatem, constantiam. Sed una e maximis momentis circa magnetes NdFeB stabilitas scelerisque eorum est. Calor caliditas destrui potest campi magnetici, noti demagnetizationis, reducendi functionem suam. Unde necesse est intelligere effectus caliditatis in magnetibus NdFeB et temperaturam maximam determinare, quam sine demagnetizatione sustentare possunt.

Numquid Maximum Temperature Demagnetize NdFeB Magnets?

Ita, caliditas caliditas potest facere magnetes NdFeB demagnetizare. Demagnetizationis magneticarum NdFeB effectus est ex ambigua scelerisque in campo magnetico. In specie summae temperaturae plus energiae scelerisque adesse causat, quae atomos celerius moveat quam in inferioribus temperaturis. Aucta vis scelerisque ambigua in propinquo magnetico creat, deducto ad vim campi magnetici et tandem demagnetizationis.

Quid est maximum Temperature Quod NdFeB Magnets Sine Demagnetizatione resistere potest?

Maxima temperatura, quam magnetes NdFeB sustinere possunt sine demagnetizatione, variis ex causis pendent, sicut gradus magnetis, geometriae, temperaturae operantis, et durationis. Maximus modus temperaturae in NdFeB data sheet magnetis typice specificatur, sed in genere magnetes NdFeB temperaturae usque ad 150°C sustinere possunt sine insigni reductione in magnetica perficiendi. Porro magnetes quidam gradus superiores NdFeB usque ad CC°C temperaturas operantes tolerare possunt.

Impulsum Coatings in NdFeB Magnetum Demagnetizationem ad Maximum Temperature

Magnetes ndFeB valde obnoxii sunt corrosioni ac propterea variis materiis obductis ad eas a ambitu defendendas. Dum hae coatinges magnetes a corrosione tueri possunt, etiam magnetis observantiam ad altas temperaturas afficere possunt. Exempli gratia, nonnullae tunicae, ut epoxy, liquefaciunt et causant magnetem multo maturius quam expectatur demagnetizere. Una e communissimis tunicis magnetum NdFeB adhibitorum est nickel-aer-nickel (Ni-Cu-Ni) tunica, quae temperaturae usque ad CC°C sustinere potest. Aliae tunicae quae caliditates tolerare possunt, aurum, argentum, et plumbum includunt.

Magnetes ndFeB sensibiles sunt ad altas temperaturas, et demagnetizationis in temperaturis fieri potest supra eorum magnitudinem maximam temperaturam operantem. Maximam temperiem quam magnetes NdFeB sine demagnetizatione ferre possunt, typice in schedula magnetis specificantur et a variis causis, quae magnetum effectus afficiunt, dependet. Ideo necesse est considerare applicationis ad temperaturam et durationem operantis et aptam ad magnetem efficiendam eligere. Diligenter harum factorum consideratione, magnetes NdFeB efficaciter adhiberi possunt in applicationibus caliditatis sine demagnetizatione.
