Magnetomotive force (mmf), Fm=NI ampere-turns (At), qhov twg N=tus naj npawb ntawm conductors (los yog tig) thiab kuv=tam sim no 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?
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 ntawm cov khoom siv hluav taws xob hauv ib qho lub tshuab nqus tsev. Magnetomotive quab yuam yog lub zog uas teeb tsa lub magnetic teb nyob rau hauv thiab ib ncig ntawm ib yam khoom.
Magnetomotive quab yuam hauv magnetic circuit yog dab tsi?
In magnetic circuit. Lub zog magnetomotive, mmf, yog analogous rau lub zog electromotive thiab tej zaum yuav suav hais tias yog qhov tseem ceeb uas teeb tsa cov flux. Lub mmf yog sib npaug rau ib tug xov tooj ntawm lem ntawm xaim nqa cov hluav taws xob tam sim no thiab muaj units ntawm ampere-tig.
MMF poob nyiaj li cas?
Lub mmf poob ntawm huab cua sib txawv yog xam raws li HGlG=(1/410 7)(0.0005)=397.9 Ntawm.
Dab tsi yog lub zog hlau nplaum?
Lub zog tawm los ntawm cov hlau nplaum uas txiav txim siab los ntawm cov lej ntawm tag nrho cov kab ntawm cov hlau nplaum tam sim no hauv cov hlau nplaum

Yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau pom kev pom?
Txawm li cas los xij, corneal collagen cross-linking - cov txheej txheem qib siab tau pom zoo los ntawm US Food and Drug Administration (FDA) hauv xyoo 2016 - tuaj yeem txhim kho qhov pom kev hauv cov neeg mob txhua hnub nyoog. Corneal collagen cross-linking (CXL) tsis yog kho rau keratoconus, tab sis nws tuaj yeem pab tiv thaiv tus mob kom tsis txhob mob hnyav.
Formula rau tangential quab yuam?
thawb ntawm qhov deb dua ntawm tus pin txhais tau tias koj siv lub zog loj dua. Xav txog tias tus kws kho tsheb thawb qhov kawg ntawm 0.3-meter-ntev torque wrench siv 9 Newton-meters ntawm lub zog. Xam lub zog tangential. F_t=τ/R=9 Newton-meters/0.
Puas centrifugal quab yuam ua rau tidal bulge?
Nkauj tawm tshiab nyob deb ntawm lub ntiaj teb tsis yog los ntawm lub zog centrifugal. Nws yog tshwm sim los ntawm qhov tseeb tib yam qhov ze-sab bulge yog tshwm sim los ntawm: lub hli lub ntiajteb txawj nqus. Tsis tas li ntawd, cov teebmeem tidal tsis yog tshwm sim los ntawm tag nrho lub zog ntawm lub ntiajteb txawj nqus zoo li lub ntiaj teb orbits.
Nyob rau hauv quab yuam kom suav nrog?
Kev txhais lub zog kom suav nrog: tus neeg muaj zog thiab tsis tuaj yeem tsis quav ntsej Thaum nws yeej nws thawj peb qhov kev sib tw, lwm tus players pom tau tias nws yog lub zog rau yuav suav nrog. Puas yog quab yuam suav nrog lossis quab yuam tsis suav nrog?
Vim li cas iris nyob rau hauv tseem quab yuam?
Nyob rau hauv ntu no, txawm li cas los xij, cov kiv cua tau kawm vim li cas Iris tsis tuaj. … Nws tau txais kev phem heev uas Deon, Tseem Ceeb, swooped los tiv thaiv Iris los ntawm kev siv nws lub peev xwm los tswj nws kom tsis txhob hla dhau ntau lub dav hlau ntawm sab cev nqaij daim tawv, txav nws mus rau "
