Magnetic Field vs Sib Nqus Flux
Nyob hauv qhov chaw nyob ib puag ncig cov khoom sib nqus muaj cov kab sib nqus emanating nyob rau hauv ib qho kev npaj hu ua magnetic teb ntawm cov khoom. Cov kab sib nqus no nyob rau hauv ib cheeb tsam tau piav qhia siv cov sib nqus flux. Cov quab yuam yog siv zog txav hluav taws xob nyob ib ncig ntawm cov hlau nplaum no. Tsiv nqi hais tau deflected raws cov kev taw qhia ntawm magnetic kab. Qee cov neeg tsis meej pem los ntawm cov ntsiab lus ntawm magnetic teb thiab magnetic flux vim qhov sib xws ntawm lawv. Txawm li cas los xij muaj qhov sib txawv uas yuav tau qhia hauv kab lus no.
Qhov ntom ntawm cov kab sib nqus flux muaj feem cuam tshuam nrog lub zog ntawm cov hlau nplaum. Raws li lawv ncaj qha proportional, peb muaj peev xwm xav tias lub zog ntawm magnetic teb nrog qhov ceev ntawm magnetic flux kab. Cov kab flux no yog qhov ntom ntom ntawm cov ncej hlau nplaum, thiab raws li ib qho txav deb ntawm cov ncej, cov kab sib nqus flux sib txawv thiab ua kom tsawg dua. Qhov ceev ntawm magnetic flux no yog vector kom muaj nuj nqis uas ua rau lub magnetic teb. Lub zog uas tau ntsib los ntawm kev txav mus los ntawm qhov chaw sib nqus yog muab los ntawm qhov sib npaug hauv qab no.
F=qv X B=qvB
Q yog tus nqi ntawm qhov twg, v yog nws qhov nrawm thiab B yog qhov sib nqus flux vector.
Kev sib raug zoo ntawm magnetic teb thiab magnetic flux yog muab los ntawm cov kab zauv hauv qab no
B=u X H=uH
B yog qhov sib nqus flux, H yog qhov ntom ntawm magnetic teb thiab u yog qhov permeability ntawm nruab nrab.
Muaj lwm qhov sib npaug ntsig txog magnetic flux thiab magnetic teb
Magnetic Flux=B X A=BA
Qhov B yog qhov chaw sib nqus thiab A yog thaj tsam perpendicular rau magnetic teb
In luv:
Qhov Sib Txawv Ntawm Sib Nqus Teb thiab Sib Nqus Flux
• Txhua yam khoom sib nqus muaj qhov sib nqus hauv thaj tsam ib puag ncig uas xav tau los ntawm kev txav cov khoom siv.
• Sib nqus teb yog piav qhia siv cov kab sib nqus emanating hauv cov qauv teeb
• Sib nqus flux yog ib lub tswv yim hais txog lub zog ntawm magnetic teb
• Sib nqus flux yog muab los ntawm cov khoom ntawm magnetic teb thiab lub perpendicular yog tias nws nkag mus.
