Electricity vs Magnetism
Hluav taws xob thiab hlau nplaum yog ob lub ntsiab lus tseem ceeb uas tau tham hauv physics. Cov ntsiab lus ntawm hluav taws xob thiab hlau nplaum yog qhov tseem ceeb hauv ntau qhov chaw sib nrug ntawm physics, thiab. Hluav taws xob yog lub zog ntawm qhov xwm txheej uas yog lub luag haujlwm rau cov hluav taws xob tam sim no thiab hluav taws xob. Magnetism yog lub zog ntawm qhov xwm txheej uas yog lub luag haujlwm rau cov hlau nplaum thiab cov hlau nplaum. Hauv tsab xov xwm no, peb yuav tham txog dab tsi hluav taws xob thiab hlau nplaum yog, lub ntsiab lus ntawm hluav taws xob thiab hlau nplaum, kev sib raug zoo ntawm hluav taws xob thiab hlau nplaum, thiab thaum kawg qhov txawv ntawm hluav taws xob thiab hlau nplaum.
Hluav taws xob
Hluav taws xob yog lub zog tseem ceeb hauv qhov xwm txheej thaum nws ua ke nrog cov hlau nplaum. Hluav taws xob tuaj yeem txhais tau tias yog qhov tshwm sim uas tshwm sim vim yog hluav taws xob. Qhov no yog ib lub tswv yim intuitive thiab tsis tuaj yeem txhais tau zoo. Lub zog hluav taws xob yog lub zog 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. Lub zog hluav taws xob tuaj yeem yog qhov txaus nyiam lossis xav tsis thoob. Yog tias ob qho kev them nqi yog 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.
Magnetism
Magnetism yog qhov tshwm sim uas tsim los ntawm kev txav hluav taws xob. Cov hlau nplaum kuj muaj dual. Cov ncej hlau nplaum tsim los ntawm kev txav hluav taws xob raug hu ua cov ncej qaum teb thiab cov ncej qab teb. Sib nqus ncej yeej ib txwm tshwm sim ua khub. Tsis muaj magnetic monopoles. Magnetism, nrog rau hluav taws xob tsim hluav taws xob electromagnetism uas yog ib qho ntawm plaub lub zog ntawm qhov xwm txheej. Sib nqus dipoles tsim magnetic teb. Cov hlau nplaum zoo sib xws tawm tsam ib leeg qhov sib txawv ntawm cov hlau nplaum sib nqus nyiam ib leeg.
Qhov txawv ntawm Hluav Taws Xob thiab Magnetism yog dab tsi?
• Hluav taws xob tuaj yeem muaj nyob rau hauv cov nqi hluav taws xob zoo li qub (txhim hluav taws xob zoo li qub) lossis cov nqi txav (tam sim no hluav taws xob) whereas magnetism tsuas yog tam sim no thaum muaj nqi txav.
• Cov nqi hluav taws xob tuaj yeem tshwm sim hauv monopoles. Qhov tsis zoo thiab tus nqi zoo tsis tas yuav tshwm sim hauv khub. Sib nqus monopoles tsis tuaj yeem nyob; Sib nqus ncej yeej ib txwm ua nyob rau hauv opposite khub.
