Magnetic Force vs Electric Force
Sib nqus rog thiab hluav taws xob yog ob lub zog uas tshwm sim hauv qhov xwm txheej. Hluav taws xob yog cov rog uas tshwm sim vim hluav taws xob thaum lub zog sib nqus yog cov rog uas tshwm sim vim cov hlau nplaum dipoles. Lub zog hluav taws xob thiab cov hlau nplaum sib xyaw ua ke muab lub zog hluav taws xob, uas yog ib qho ntawm plaub lub zog ntawm qhov xwm txheej. Lwm peb lub zog tseem ceeb yog lub zog gravitational, tsis muaj zog nuclear, thiab muaj zog nuclear zog. Cov ntsiab lus ntawm cov hlau nplaum thiab cov hluav taws xob hluav taws xob tau siv rau hauv thaj chaw xws li mechanics, electromagnetic, electrostatics, magnetostatic thiab lwm yam kev lag luam ntsig txog physics. Hauv tsab xov xwm no, peb yuav tham txog dab tsi yog hluav taws xob thiab hluav taws xob sib nqus, cov ntsiab lus ntawm ob qho no, lawv cov kev siv, qhov sib xws thiab qhov sib txawv ntawm cov hluav taws xob thiab cov hlau nplaum sib nqus.
Hluav taws xob
Hluav taws xob yog cov rog uas tshwm sim vim hluav taws xob. Muaj ob hom kev them nqi hluav taws xob. Lawv yog cov zoo thiab tsis zoo. Tus nqi hluav taws xob tau piav qhia los ntawm qhov hluav taws xob cuam tshuam nrog nws. Cov hluav taws xob hluav taws xob thiab hluav taws xob hluav taws xob zoo li qhov teeb meem "nqaij qaib thiab qe". Ib tug yuav tsum piav rau lwm tus. Lub teb hluav taws xob tau hais tias yog tsim los ntawm tag nrho cov nqi hluav taws xob txawm tias lawv tsiv los yog nyob ruaj ruaj. Ib qho hluav taws xob tuaj yeem tsim tau siv txhua lub sijhawm sib txawv ntawm cov hlau nplaum.
Muaj ntau yam tseem ceeb ntawm cov hluav taws xob. Cov no yog hluav taws xob siv hluav taws xob, hluav taws xob muaj peev xwm thiab hluav taws xob flux ceev. Lub peev xwm hluav taws xob los ntawm tus nqi taw tes yog muab los ntawm V=Q / 4πεr. Lub zog hluav taws xob ntawm tus nqi ntawm tus nqi q muab tso rau hauv qhov hluav taws xob yog muab los ntawm F=V q qhov twg V yog qhov muaj peev xwm ntawm qhov ntawd.
Hluav taws xob muaj peev xwm ua tau ntxim nyiam lossis xav tsis thoob. Yog tias ob qho tib si ntawm cov nqi tib yam (tsis zoo lossis qhov zoo), cov rog yog qhov tsis txaus ntseeg, yog tias lawv muaj ntau hom rog yog qhov txaus nyiam.
Magnetic Force
Magnetic force yog lub zog uas tsim los ntawm ob lub hlau nplaum. Ib lub hlau nplaum tsis tuaj yeem tsim lub zog sib nqus. Sib nqus rog yog tsim thaum cov hlau nplaum, cov khoom sib nqus, lossis cov xaim nqa tam sim no muab tso rau ntawm qhov chaw sib nqus sab nraud.
Kev quab yuam vim cov hlau nplaum tsis sib xws yog yooj yim los laij, tab sis cov rog vim qhov sib nqus tsis sib xws yog qhov nyuaj. Sib nqus rog yog ntsuas hauv Newton. Cov zog no yeej ib txwm sib koom.
Ib tug hlau nplaum muaj ob tug ncej. Lawv yog South Pole thiab North Pole. Cov ncej zoo sib xws repulse ib leeg, whereas opposite ncej nyiam ib leeg.
Qhov txawv ntawm Hluav Taws Xob thiab Sib Nqus Hluav Taws Xob yog dab tsi?
• hluav taws xob tuaj yeem tsim tau los ntawm qhov chaw nres tsheb lossis txav hluav taws xob, qhov sib nqus rog tuaj yeem tsim los ntawm kev txav mus los xwb.
• Sib nqus quab yuam ntawm tus nqi txav yog ib txwm ib txwm ua rau kev taw qhia ntawm kev txav mus los thiab qhov chaw sib nqus thaum lub zog los ntawm lub tshav pob hluav taws xob ntawm tus nqi txav mus ib txwm nyob rau tib lub sijhawm mus rau qhov hluav taws xob thiab tsis nyob ntawm qhov kev taw qhia ntawm kev txav chaw.
