History. Lub sij hawm magnetomotive quab yuam yog coined los ntawm Henry Augustus Rowlandhauv 1880.
Leej twg muab txoj cai ntawm magnetic force?
Charles-Augustin de Coulomb yog thawj tus kws tshaj lij Fab Kis thiab tub rog kws tshaj lij uas tau qhia txog Txoj Cai Sib Nqus Sib Nqus hauv 1785 lub npe hu ua Coulomb's Inverse Square Law of magnetic force lossis Coulomb's Law of magnetic zog. Nws sawv cev rau qhov muaj nuj nqis ntawm lub zog rau ob lub ntsiab lus sib cais.
Magnetomotive force formula yog dab tsi?
Electromagnetism and magnetic circuits
Magnetomotive force (mmf), Fm=NI ampere-turns (At), qhov twg N=tus naj npawb ntawm cov conductors (los yog tig) thiab kuv=tam sim no hauv amperes.
Lub zog magnetomotive thiab nws chav tsev yog dab tsi?
Lub zog magnetomotive, mmf, yog qhov sib piv rau lub zog hluav taws xob thiab tej zaum yuav raug suav hais tias yog qhov teeb meem uas teeb tsa cov flux. Lub mmf yog sib npaug rau ib tug xov tooj ntawm lem ntawm xaim nqa hluav taws xob tam sim no thiab muaj units ntawm ampere-tig.
