Abstract

Device for correcting the effect of an external stress overload affecting a ferromagnetic component, comprising: the ferromagnetic component, having at least one magnetic field, and a magnetic field sensor, and at least one coil, being arranged around the magnetic field sensor and/or around the ferromagnetic component, and generating a magnetic field, with the field providing an oscillating magnetic field and a magnetic flux density of at least 30 Gauss.

Claims (31)

1. A device configured to correct an effect of an external stress overload affecting a ferromagnetic component, the device comprising:

the ferromagnetic component having at least one magnetized region;

at least two magnetic field sensors; and

at least one coil being arranged around the at least two magnetic field sensors and the ferromagnetic component, the at least one coil configured to generate a magnetic field comprising an oscillating magnetic field and a magnetic flux density of at least 30 Gauss.

2. The device according to claim 1 , wherein each of the at least two magnetic field sensors has a variable sensitivity.

3. The device according to claim 1 , wherein the at least one coil is activated at at least one of regular intervals, while there is a malfunction in a system encompassing the ferromagnetic component, or while the system encompassing the ferromagnetic component is restarted.
