Yog, nws yog ua tau rau ib hlau nplaum ruaj khov rau poob nws hlau nplaum . Muaj peb txoj hauv kev rau qhov tshwm sim: 2) Los ntawm demagnetizing magnetic teb: hlau nplaum ruaj khov nthuav tawm tus yam ntxwv hu ua coercivity, uas yog lub peev xwm ntawm cov khoom siv los tiv thaiv kev demagnetized los ntawm kev siv magnetic teb.

Kuj tseem paub yog, cov hlau nplaum puas poob hlau nplaum lub sijhawm?

Demagnetization yog txheej txheem qeeb tab sis hlau nplaum yuav poob lawv lub zog dhau sijhawm . Qhov no feem ntau tshwm sim nyob rau hauv ob txoj kev. Yog li hu ua mus tas li hlau nplaum yog tsim los ntawm cov ntaub ntawv ua los ntawm magnetic domains, nyob rau hauv uas atoms muaj electrons uas nws spines ua ke nrog ib leeg.

Ib tug kuj yuav nug, ntev npaum li cas cov hlau nplaum nyob ruaj khov? A hlau nplaum ruaj khov , yog khaws cia thiab siv rau hauv kev ua haujlwm zoo, yuav khaws nws cov hlau nplaum rau xyoo thiab xyoo. Piv txwv li, nws yog kwv yees tias a neodymium hlau nplaum poob kwv yees li 5% ntawm nws cov hlau nplaum txhua 100 xyoo.

Ntxiv mus, vim li cas cov hlau nplaum ruaj khov poob nws cov hlau nplaum?

Cov hlau nplaum ruaj khov ua tau poob lawv hlau nplaum yog hais tias lawv poob los yog banged txaus los tsoo lawv cov thawj tawm ntawm kev sib raug zoo. Yog vim li cas uas yuav nyuaj rau pob ib daim hlau thiab ua nws magnetic vim tus txoj kev vibrations propagate nyob rau hauv tus khoom.

Cov hlau nplaum puas ua haujlwm tas mus li?

Theoritically ib hlau nplaum yuav muaj nws cov khoom sib nqus Mus ib txhis . Qhov no tshwm sim vim yog koj khaws ib hlau nplaum tsis tawm tsam nws lub zog sib nqus thiab ntawm qhov kub ntawm 0K ces nws yuav khaws nws lub zog sib nqus mus ib txhis.
