Teeb yog electromagnetic nthwv dej: qhov no tau pom los ntawm Maxwell nyob rau hauv 1864, raws li ib tug tshwm sim kev sib npaug c = 1/(e0m0)1/2 Luas = 2,998 x 108m / s tau pom, txij li qhov ceev ntawm teeb tau raug ntsuas kom raug los ntawm qhov ntawd, thiab nws qhov kev pom zoo nrog c tsis zoo li yuav yog qhov xwm txheej.

Ib yam li ntawd, koj tuaj yeem nug, leej twg tsim Maxwell qhov sib npaug?

Kev ywj pheej ntawm Heaviside, Heinrich Hertz kuj tau muab cov qauv yooj yim ntawm Maxwell's Equations , txawm tias tom qab ntawd nws tau lees paub qhov ua ntej ntawm Heaviside txoj haujlwm. Xyoo 1888 Hertz tau ua nws txoj haujlwm tseem ceeb tshaj plaws nrog kev tshawb pom ntawm xov tooj cua nthwv dej.

plaub Maxwell qhov sib npaug yog dab tsi? Maxwell qhov sib npaug yog ib txheej ntawm plaub sib txawv kev sib npaug uas tsim lub hauv paus theoretical rau piav txog classical electromagnetism: Gauss txoj cai: Cov nqi hluav taws xob tsim hluav taws xob. Gauss txoj cai rau hlau nplaum: Tsis muaj hlau nplaum monopoles. Qhov sib nqus flux hla ntawm qhov chaw kaw yog xoom.

Kuj paub, Maxwell thawj kab zauv yog dab tsi?

1. Qhov no kev sib npaug hais tias qhov hluav taws xob ua haujlwm zoo los ntawm qhov chaw ntim ib lub ntim yog sib npaug rau tag nrho cov nqi hauv lub ntim. Kom nco ntsoov daim ntawv tseem ceeb ntawm Maxwell's Equation No. 1, xav tias ib tug nqi q, nyob rau hauv ib lub ntim, yuav tsum sib npaug zos rau lub ntim nqi ceev, r, lub sij hawm lub ntim.

Maxwell nrhiav tau nws qhov sib npaug li cas?

Hauv nws thawj zaug sim, ib daim ntawv 1855 hu ua "Rau Faraday's Lines of Force," Maxwell tsim ib qho qauv los ntawm kev sib piv, qhia tias kev sib npaug uas piav qhia txog cov kua dej tsis txaus kuj tuaj yeem siv los daws cov teeb meem uas tsis hloov hluav taws xob lossis cov chaw sib nqus.
