Lub tog raj kheej hlau nplaum nrog qhov - Chaw tsim tshuaj paus ntawm Tuam Tshoj | Fullzen

Bar hlau nplaum thiab cylindrical hlau nplaum yog ob qho tib si rau cov hlau nplaum ruaj khov, tab sis lawv muaj qhov sib txawv ntawm lawv cov duab thiab cov khoom sib nqus:

1. Cov duab
2. Magnetization Direction
3. Sib Nqus Field Distribution
4. Daim ntawv thov
5. Kov thiab Tsim

Ob leeg bar hlau nplaum thiab cylindrical hlau nplaum muaj lawv qhov tshwj xeeb zoo thiab kev siv. Qhov kev xaiv ntawm lawv yog nyob ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov, suav nrog cov qauv sib nqus qhov xav tau, qhov txwv loj, thiab lwm yam kev xav txog kev ua haujlwm.

Yog, muaj ib qho chaw sib nqus hauv cov hlau nplaum cylindrical. Lub xub ntiag thiab cov yam ntxwv ntawm cov hlau nplaum hauv lub tog raj kheej yog nyob ntawm tus qauv magnetization thiab cov khoom siv ntawm lub tog raj kheej.

Yog lawm, hlau nplaum tuaj yeem poob lawv lub zog thaum lub sijhawm vim muaj ntau yam. Qhov tshwm sim no hu ua magnet decay los yog demagnetization. Tus nqi ntawm cov hlau nplaum poob nws lub zog yog nyob ntawm cov khoom siv hlau nplaum, kev tsim khoom zoo, kev siv, thiab ib puag ncig yam. Nov yog qee qhov laj thawj vim li cas hlau nplaum yuav poob lawv lub zog:

1. Kub
2. Lub cev poob siab
3. Sab nraud Sib Nqus Fields
4. Corrosion
5. Kev laus
6. Kev khaws cia tsis raug
7. Kev tsim khoom tsis zoo
8. Mechanical Stress

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias thaum cov hlau nplaum tuaj yeem poob lawv lub zog, tus nqi ntawm kev lwj thiab qhov poob yog nyob ntawm cov khoom siv hlau nplaum tshwj xeeb thiab kev siv. Cov hlau nplaum zoo uas ua los ntawm cov ntaub ntawv muaj zog thiab kev saib xyuas zoo yog qhov muaj peev xwm tswj tau lawv lub zog ntev dua. Txawm li cas los xij, tag nrho cov hlau nplaum yuav ib txwm muaj qee qhov kev lwj ntawm lub sijhawm.
