What is Weber in physics?


Open in App
Solution

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, ϕ=BAcosθ,
    Where,

ϕ= magnetic flux and the unit of magnetic flux is Weber (Wb) or Tesla meter squared (Tesla) (Tm2). 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.

cosθ = The angle formed by the magnetic flux and the planar area

5. So, the unit of weber iskgm2s-2A-1, and

6. The dimension of Weber is [ML2T-2A-1].
