In physics, the 'weber' (symbol: Wb) is the SI unit of magnetic flux. It is named after the German physicist Wilhelm Eduard Weber (1804 - 1891) and was established by the IEC in 1930 [1].

Definition

The weber may be defined in terms of Faraday's law, which relates a changing magnetic flux through a loop to the electric field around the loop. A change in flux of one weber per second will induce an electromotive force of one volt.
In SI base units, the dimensions of the weber are $dfrac\{mbox\{kg\}\; cdot\; mbox\{m\}^2\}\{mbox\{s\}^2\; cdot\; mbox\{A\}\}$. In derived units, they are volt-seconds $(mbox\{V\}\; cdot\; mbox\{s\})$.
The weber is a large unit, equal to 1 T m² = 10⁸ maxwells.
