Electromagnetism thiab magnetic circuits Magnetomotive force (mmf), Fm=NI ampere-turns (At), qhov twg N=tus naj npawb ntawm conductors (los yog lem) thiab kuv=tam sim no nyob rau hauv amperes. Txij li thaum 'tig' tsis muaj units, SI unit ntawm mmf yog ampere, tab sis kom tsis txhob muaj kev tsis sib haum xeeb 'ampere-turns', (A t) yog siv nyob rau hauv tshooj no.
Lub zog magnetomotive dab tsi yog nws chav tsev?
Magnetomotive force yog lub zog uas teeb tsa lub chaw sib nqus hauv thiab ib puag ncig ib puag ncig. … Chav tsev ntawm lub zog magnetomotive yog lub ampere-tig, sawv cev los ntawm ib qho chaw ruaj khov, ncaj qha hluav taws xob ntawm ib lub ampere ntws hauv ib lub voj voog ib zaug ntawm cov khoom siv hluav taws xob hauv lub tshuab nqus tsev.
Koj suav H teb li cas?
Lub ntsiab lus ntawm H yog H=B/μ − M, qhov B yog qhov sib nqus flux ntom, ntsuas ntawm qhov tseeb sib nqus hauv cov khoom suav tias yog qhov concentration ntawm magnetic teb kab, los yog flux, ib chav tsev cross-sectional cheeb tsam; μ yog qhov sib nqus permeability; thiab M yog magnetization.
MMF txhais li cas los ntawm formula?
The magnetomotive force (mmf) cov qauv qhia los ntawm kev sib raug zoo hauv qab no. F=A-t. Lub kauj muaj 10 tig thiab 1A ntawm tam sim no ua tib yam sib nqus flux lossis quab yuam raws li ib qho muaj 5 tig thiab 2A tam sim no vim tias cov ampere-tig yog tib yam.
Yuav ua li cas xam qhov tsis kam?
Kev tsis txaus siab tau txais by faib qhov ntev ntawm txoj kev sib nqus l los ntawm lub sijhawm permeability ntawm thaj chaw hla ntu A; Yog li r=l / μA, Greek tsab ntawv mu, μ, cim lub… Qhov tsis txaus siab ntawm ib lub voj voog sib nqus yog qhov sib piv rau qhov tsis kam ntawm hluav taws xob circuit.
