Txoj kev daws teeb meem. Kev soj ntsuam: Hysteresis poob yog ncaj qha proportional rau qhov zaus ntawm daim teb, sib nqus flux siv, thiab ntim ntawm cov khoom. Hysteresis poob tsis nyob ntawm Neel qhov kub.
Yam dab tsi cuam tshuam rau hysteresis poob?
Hysteresis poob yog tshwm sim los ntawm cov hlau nplaum thiab demagnetization ntawm cov tub ntxhais uas tam sim no ntws mus rau pem hauv ntej thiab thim rov qab. Raws li lub zog magnetizing (tam sim no) nce, qhov sib nqus flux nce.
Hysteresis nyob ntawm dab tsi?
Hysteresis yog kev vam khom ntawm lub xeev ntawm qhov system ntawm nws keeb kwm. Piv txwv li, ib lub hlau nplaum yuav muaj ntau tshaj ib lub sij hawm sib nqus nyob rau hauv ib qho chaw sib nqus, nyob ntawm seb qhov chaw hloov pauv li cas yav dhau los.
Dab tsi yog qhov cuam tshuam ntawm qhov poob tam sim no nyob ntawm?
Yog li peb pom eddy tam sim no poob ib chav tsev ntim ntawm cov khoom ncaj qha nyob ntawm lub square ntawm zaus, flux ceev thiab thickness ntawm phaj. Tsis tas li ntawd nws yog inversely proportional rau lub resistivity ntawm cov khoom. Lub hauv paus ntawm cov khoom siv yog tsim los siv cov phaj nyias hu ua laminations.
Hysteresis poob nyob ntawm qhov zaus li cas?
Hysteresis poob yuav nce nrog zaus, thiab lawv yog cov khoom loj tshaj plaws hauv cov ntaub ntawv uas muaj kev rov zoo siab. Cov ntaub ntawv no, ib zaug magnetized, zoo li khaws lawv cov hlau nplaum. Nwsxav tau lub zog ntau dua los demagnetize lawv dua li cov uas tsis tshua muaj retentivity.
