Sib nqus tivthaiv ntau lawm yuav ua li cas kom nkag siab lub ntsiab lus txhais ntawm cov hlau nplaum

Sib nqus tivthaiv ntau lawm Yuav ua li cas to taub lub ntsiab txhais lub ntsiab lus ntawm magnetic? Yooj yim muab, hlau nplaum yog qhov cuam tshuam ntawm lub zog sib nqus ntawm cov khoom uas muab tso rau hauv qhov chaw tsis sib xws. Nyob rau hauv tib yam uas tsis yog-uniform magnetic teb, qhov sib nqus lub zog ntawm cov khoom yog txiav txim los ntawm cov kev taw qhia thiab lub zog ntawm lub sib nqus quab yuam ib unit loj ntawm cov khoom. Vim hais tias tej yam khoom yog sib nqus, tej yam khoom nyob rau hauv ib tug non-uniform magnetic teb yuav raug cuam tshuam los ntawm lub magnetic quab yuam.

Qhov tiag tiag muaj nyob rau hauv qhov chaw nyob ib ncig ntawm tus ncej tsis yog magnetic teb kab, tab sis ib daim teb, uas peb hu ua magnetic teb. Kev sib nrig sib nyiam ntawm cov khoom sib nqus yog ua los ntawm cov hlau nplaum. Peb paub tias muaj universal gravitation ntawm qhov teeb meem, nws yog ib tug gravitational teb.

Ib qho chaw sib nqus zoo ib yam, ib qho chaw uas nyob ib puag ncig ntawm tus ncej. Lub zog ntawm cov hlau nplaum tuaj yeem sawv cev los ntawm cov xov tooj ntawm kev xav ntawm cov kab sib nqus ntawm lub zog. Lub magnetic teb muaj zog nyob qhov twg cov magnetic teb kab yog ntom, thiab cov magnetic teb tsis muaj zog qhov twg cov magnetic teb kab yog sparse. Tus naj npawb ntawm cov kab hlau nplaum hla dhau ib ntu yog hu ua magnetic flux density.

Tsiv cov khoom siv hluav taws xob hauv qhov chaw sib nqus yog raug rau lub zog hu ua Lorentz force. Lub zog ntawm cov hlau nplaum yog txiav txim siab los ntawm qhov loj ntawm Lorentic quab yuam ntawm tib qhov nqi ntawm cov khoom sib nqus. Tesla yog SI unit ntawm magnetic flux ntom. Qhov sib nqus flux ntom yog qhov yooj yim ntawm lub cev kom piav qhia lub cev sib nqus, thiab lub zog sib nqus yog cov kev sib nqus kom piav qhia qhov sib nqus. Tesla (Tesla, N) (1886 ~ 1943) yog Croatian-Asmeskas hluav taws xob engineer uas tau tsim cov transformers thiab AC motors.

Cov hlau nplaum ntawm cov teeb meem tsis yog tsuas yog ubiquitous, tab sis kuj muaj ntau haiv neeg, thiab yog li ntawd tau lug kawm thiab siv. Qhov teeb meem ze rau peb lub cev thiab ib puag ncig, raws li qhov teeb meem nyob rau hauv ntau lub hnub qub thiab lub cev interstellar, lub atoms, atomic nuclei thiab elementary hais nyob rau hauv lub microscopic ntiaj teb no, thiab txhua yam ntawm cov ntaub ntawv nyob rau hauv lub macroscopic ntiaj teb no, txhua yam muaj magnetic zog. ib hom lossis lwm yam.
