Cov magnitude ntawm magnetic teb 6.00 x 10-6 T, uas tuaj yeem sau ua (micro-Tesla). Kev taw qhia ntawm lub magnetic teb tuaj yeem txiav txim siab siv "txoj cai sab xis", los ntawm taw ntiv tes xoo ntawm koj sab tes xis nyob rau hauv cov kev taw qhia ntawm qhov tam sim no.

Ua kom pom qhov no, txhais li cas los ntawm qhov loj ntawm magnetic teb?

Cov magnetic teb B yog txhais los ntawm Lorentz Force Law, thiab tshwj xeeb los ntawm Sib nqus force on ib tug txav nqi: The qhov loj ntawm lub zog yog F = qvB sinθ qhov twg θ yog lub kaum sab xis <180 degrees ntawm qhov nrawm thiab qhov magnetic teb.

Ib tug kuj yuav nug, dab tsi yog qhov magnitude thiab kev taw qhia ntawm magnetic teb? Lub zog no yog ib qho tseem ceeb tshaj plaws paub. Cov kev taw qhia ntawm cov hlau nplaum quab yuam ntawm tus nqi txav mus yog nyob rau ntawm lub dav hlau tsim los ntawm v thiab B thiab ua raws li txoj cai tes-1 (RHR-1) raws li qhia. Cov qhov loj ntawm lub zog yog proportional rau q, v, B, thiab lub sine ntawm lub kaum sab xis ntawm v thiab B.

Xav txog qhov no, dab tsi yog magnetic field formula?

Cov kev sib npaug rau cov magnetic teb lub zog (magnitude) uas ua los ntawm ib tug ntev ncaj tam sim no-nqa hlau yog: B = Μ0I2πr. Rau ib txoj kab ncaj nraim uas kuv yog qhov tam sim no, r yog qhov luv tshaj plaws ntawm cov hlau, thiab qhov tsis tu ncua 0= 4p107 T⋅m / A yog qhov permeability ntawm qhov chaw dawb.

Dab tsi yog magnetic teb thiab nws chav tsev?

Magnetic Field Units Ib qho me me magnetic teb unit yog Gauss (1 Tesla = 10,000 Gauss). Cov Sib nqus ntau B uas yog hu ua " magnetic teb "ntawm no qee zaum hu ua" Sib nqus flux ceev". chav tsev Lub npe rau Tesla yog Webers ib meter squared, nrog rau Weber yog tus chav tsev ntawm Sib nqus flux.
