韦伯是国际单位制中磁通量的单位[1],缩写Wb,是以德国物理学家威廉·韦伯的名字命名的。


1Wb = 1V·s = 108 Mx (馬克士威)

韦伯可以用法拉第电磁感应定律来推导,即平均每秒一個韦伯的變化可以產生一伏特的電動勢[2]


韦伯可以用不同單位的乘積來表示


Wb=kg⋅m2s2⋅A=V⋅s=H⋅A=T⋅m2=JA=108Mxdisplaystyle mathrm Wb =dfrac mathrm kg cdot mathrm m ^2mathrm s ^2cdot mathrm A =mathrm V cdot mathrm s =mathrm H cdot mathrm A =mathrm T cdot mathrm m ^2=dfrac mathrm J mathrm A =10^8mathrm Mx

其中
Wb = 韦伯,

V = 伏特,

T = 特斯拉,

J = 焦耳,

m = 公尺,

s = 秒,

A = 安培,

H = 亨利,

Mx = 馬克士威.
