## Senses

### 1. unit of magnetic flux

noun · CEFR C2 · Technical

a unit used by scientists to measure the strength of a magnetic field passing through an area.

For teachers: the SI derived unit of magnetic flux; specifically, the flux linking a circuit of one turn that produces an electromotive force of one volt when reduced uniformly to zero in one second.

- The scientist recorded the magnetic flux in webers to ensure the data was accurate.
- In the laboratory report, the magnetic flux density was calculated by dividing the total number of webers by the surface area of the coil.

Usage: The noun is countable and is usually abbreviated as 'Wb' in scientific notation.

Teaching tip: This is a highly specialized term; learners only need it for physics or engineering contexts.

## Examples

- The scientist measured the magnetic flux in webers.
- Engineers calculated the total magnetic flux in webers to determine the efficiency of the new transformer core.
- In the International System of Units, one weber is equivalent to one volt-second, providing a standardized measure for magnetic flux across various physical and engineering applications.
