(Qhov no txhais ntawm Sib nqus flux vim B feem ntau hu ua Sib nqus flux density.) Cov cim tsis zoo sawv cev rau qhov tseeb tias txhua qhov tam sim no tsim los ntawm kev hloov pauv magnetic teb nyob rau hauv ib tug coil tsim ib magnetic teb uas tawm tsam qhov kev hloov pauv hauv magnetic teb uas induced nws.

Ua kom pom qhov no, B hauv magnetic teb yog dab tsi?

Sib nqus teb Units A me dua magnetic teb unit yog Gauss (1 Tesla = 10,000 Gauss). Cov Sib nqus kom muaj nuj nqis B uas yog hu ua " magnetic teb "ntawm no qee zaum hu ua" Sib nqus Ib lub npe qub rau Tesla yog Webers ib meter squared, nrog Weber yog chav tsev ntawm Sib nqus flux.

Ib tug kuj yuav nug, yog vim li cas magnetic flux density B? Hauv SI units, B ntsuas hauv teslas ( cim : T) thiab sib npaug Φ B ( sib nqus flux ) yog ntsuas hauv webers ( cim : Wb) so that a flux ceev 1 Wb/m2 yog 1tl. Chav tsev SI ntawm tesla yog sib npaug rau (newton. H- teb ntsuas hauv amperes ib meter (A / m) hauv SI units, thiab hauv oersteds (Oe) hauv cgs units.

Raws li txoj cai, dab tsi ua rau muaj magnetic teb?

Peb ntiaj chaw magnetic teb ntseeg tau tias yog tsim los tob rau hauv lub ntiaj teb lub hauv paus. Lub zog Coriolis, uas tshwm sim los ntawm lub ntiaj teb tig, thiab ua rau swirling lub voj voog. Cov dej ntws ntawm cov kua hlau no ua rau cov hluav taws xob tam sim no, uas ua rau cov khoom tsim tawm magnetic teb.

B hauv physics txhais li cas?

B = magnetic flux ceev. b = beta particle. B = tswb (sound intensity) Bq = becquerel (activity) c.
