Weber

(wē`bər), river, c.125 mi (200 km) long, rising in the Uinta Mts., N central Utah, and flowing north and northwest to join the Ogden River at Ogden. The combined stream flows to the Great Salt Lake. The Weber has long been used for irrigation and is part of the U.S. Bureau of Reclamation's Weber basin project. Among the dams on the Weber are Wanship Dam (completed 1957) and Echo Dam (completed 1931).

(vay -ber) Symbol: Wb. The SI unit of magnetic flux.

Weber

 

a unit of magnetic flux in the International System of Units. It is named after the German physicist W. Weber; the Russian designation is vb and the international designation is Wb.

A weber is the magnetic flux that, upon being reduced to zero, causes the passage of 1 coulomb (C) of electricity through a 1-ohm (Ω) loop connected to it. Alternatively, a weber can be defined as the magnetic flux that, when uni- formly decreased to zero over an interval of 1 second, in- duces an electromotive force of 1 volt (V) in a closed loop through which it passes. Consequently, 1 Wb = (1Ω) · (1C), or 1 Wb = (1V) · (1 sec). Also, 1 maxwell (the unit of mag- netic flux in the cgs system) = 10-8 Wb. In the International System of Units, the weber is defined as the magnetic flux created by a uniform magnetic field having an induction of 1 tesla (T) through an area of 1 sq m normal to the direction of the field: 1 Wb = (1T) · (1 m2).

weber

[′vā·bər]
(electromagnetism)
The unit of magnetic flux in the meter-kilogram-second system, equal to the magnetic flux which, linking a circuit of one turn, produces in it an electromotive force of 1 volt as it is reduced to zero at a uniform rate in 1 second. Symbolized Wb.

weber

the derived SI unit of magnetic flux; the flux that, when linking a circuit of one turn, produces in it an emf of 1 volt as it is reduced to zero at a uniform rate in one second. 1 weber is equivalent to 108 maxwells
