The system works as follows--at small speed of the generator the induced voltage in a stator winding is low, and it causes residual magnetism in the rotor core.
If a measurement is made while the probe core is magnetized, an offset voltage proportional to the residual magnetism can occur and induce measurement error.
Both these controls and controls for electromagnetic chucks take care of a common problem with workpieces that are held magnetically: residual magnetism.
A complete line of demagnetizers for reducing residual magnetism in molds is available.
The new current probe features auto degauss (demagnetization) and auto calibration to remove residual magnetism and unwanted DC offset in the probe.

This technology uses the properly of residual magnetism to hold the fast-acting spool valves in either of two positions--open or closed.
Using the principle of residual magnetism, these digital valves allow mechanical systems to approximate the speed of microprocessors.
Reproducible results and residual magnetism lower than the geofield are among the objectives achieved.
This residual magnetism is typically undesirable and degrades performance.
The connectors are fabricated using non-magnetic material, resulting in residual magnetism rated at less than 30 gamma (nT).
