What is a weber?
The weber (Wb) is the SI unit of magnetic flux: the total amount of magnetic field passing through an area. One weber is one tesla over one square meter. By Faraday's law, a flux changing at one weber per second induces one volt in a loop around it.
Where the weber sits among magnetic flux units
The weber is number 6 of 6 on our scale of magnetic flux units, ordered from smallest to largest.
What webers are used for
- Transformer and electric motor design.
- Physics of electromagnetic induction.
- Superconducting and magnetic measurement devices (fluxmeters).
Webers in real life
- The Earth's field (about 50 µT) through 1 m²: about 50 µWb.
- A small transformer core carries flux of a few milliwebers.
History of the weber
Named after the German physicist Wilhelm Eduard Weber, who with Carl Friedrich Gauss built one of the first electromagnetic telegraphs in 1833.
