A magnet produces a magnetic field that travels from the North pole to the South pole. The total amount of field through a 2-dimensional slice is the flux, measured in units of weber. Webers per square meter indicates flux density, measured in units of tesla (T). The unit of gauss (G) also describes flux density, where 1 T = 10000 G. In millitesla, 1 mT = 10 G. Tesla is the official SI unit and used by TI data sheets, but other sources may use gauss.
