Question

What is Weber in physics?

Answer 1

Weber

1. The Weber (commonly indicated by the sign 'Wb') can be defined as the magnetic flux unit in physics.
2. One weber is equal to the magnetic flux in a square meter with a flux density of one Tesla.
3. A one-weber-per-second change in flux produces a one-volt electromotive force or an electric potential differential of one volt between two open-circuited terminals.
4. In mathematical terms, $\varphi =BA\cos \left(\theta \right)$,
   Where,

$\varphi$= magnetic flux and the unit of magnetic flux is Weber (Wb) or Tesla meter squared (Tesla) ($T{m}^2$). In this case, Tesla is equal to Weber per square meter. It is also the flux density unit.
$B$ stands for the magnetic field strength. It is measured in Ampere per meter, or A/m, in SI base units.

$A$ also stands for the perpendicular area where magnetic field lines cross.

$\cos \left(\theta \right)$ = The angle formed by the magnetic flux and the planar area

5. So, the unit of weber is$kg{m}^2{s}^{-2}{A}^{-1}$, and

6. The dimension of Weber is $\left[M{L}^2{T}^{-2}{A}^{-1}\right]$.
