DYNAMIC DEGAUSSING SYSTEM

摘要

A dynamic degaussing system includes a magnetic field sensor (136) for generating a sensor signal in response to a sensed magnetic field. The magnetic field sensor (136) is coupled to a controller (400) that produces an output signal based on the sensor signal. The controller may include feedforward and feedback control loops. The output signal of the controller controls a magnetic field generator (130) which generates a magnetic field so as to attenuate the sensed magnetic field.
