unit:WB
The SI unit of magnetic flux. "Flux" is the rate (per unit of time) at which something crosses a surface perpendicular to the flow. The weber is a large unit, equal to \(10^{8}\) maxwells, and practical fluxes are usually fractions of one weber. The weber is the magnetic flux which, linking a circuit of one turn, would produce in it an electromotive force of 1 volt if it were reduced to zero at a uniform rate in 1 second. In SI base units, the dimensions of the weber are \((kg \cdot m^2)/(s^2 \cdot A)\). The weber is commonly expressed in terms of other derived units as the Tesla-square meter (\(T \cdot m^2\)), volt-seconds (\(V \cdot s\)), or joules per ampere (\(J/A\)).
