Weber (Wb)
Working point
Weber (Wb)
SI unit of the magnetic flux. 1 Wb = 1 V×s = 10-8 maxwell. Weber, Wilhelm Eduard German physicist who, with his friend Carl Friedrich Gauss, investigated terrestrial magnetism and in 1833 devised an electromagnetic telegraph. The magnetic unit, termed a weber, formerly the coulomb, is named after him.

Working point
Intersection between loading line (see) and demagnetization curve. It is the couple of points (HW, BW), or (HW, JW), in the second quadrant of the hysteresis cycle of a permanent magnet that corresponds to its actual demagnetization field and induction. For long magnet, HW is little and BW is similar to Br. JW can be measured with Helmholtz coils (see), HW can be measured with potential coil (see).
