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 *. 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 kg·m2·s−2·A−1. In derived units, they are volt-seconds (V·s). The weber is a large unit, equal to 1 T m2 = 108 maxwells.
