In physics, the weber ( ; symbol: Wb) is the unit of magnetic flux in the International System of Units (SI). The unit is derived (through Faraday's law of induction) from the relationship (volt-second). A magnetic flux density of 1 Wb/m 2 (one weber per square metre) is one tesla. The weber is named after the German physicist Wilhelm Eduard Weber (1804–1891).
In physics, the weber ( ; symbol: Wb) is the unit of magnetic flux in the International System of Units (SI). The unit is derived (through Faraday's law of induction) from the relationship (volt-second). A magnetic flux density of 1 Wb/m 2 (one weber per square metre) is one tesla. The weber is named after the German physicist Wilhelm Eduard Weber (1804–1891). \mathrm{Wb} = \mathrm{V}{\cdot}\mathrm{s}. One weber is also the total magnetic flux across a surface of one square meter perpendicular to a magnetic flux density of one tesla; that is, \mathrm{Wb} = \mathrm{T}{\cdot}\mathrm{m}^2. Expressed only in SI base units, 1 weber is: \mathrm{Wb} = \dfrac{\mathrm{kg}{\cdot}\mathrm{m}^2}{\mathrm{s}^2{\cdot}\mathrm{A}}. The weber is used in the definition of the henry as 1 weber per ampere, and consequently can be expressed as the product of those units: \mathrm{Wb} = \mathrm{H}{\cdot}\mathrm{A}. The weber is commonly expressed in a multitude of other units: \mathrm{Wb} =\Omega {\cdot} \text{C} =\dfrac{\mathrm{J}}{\mathrm{A}} =\dfrac{\mathrm{N}{\cdot}\mathrm{m}}{\mathrm{A}}, where Ω is ohm, C is coulomb, J is joule, and N is newton.
