Weber (unit)
Encyclopedia : W : WE : WEB : Weber (unit)
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 [link].
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 = [10^8] maxwells.

| This SI unit is named after Wilhelm Eduard Weber. As for all SI units whose names are derived from the proper name of a person, the first letter of its symbol is uppercase (Wb). But when an SI unit is spelled out, it should always be written in lowercase (weber), unless it begins a sentence or is the name "degree Celsius". — Based on [The International System of Units], section 5.2.
