摘要
Magnetic structures can be used to shield electromagnetic disturbances, but it can lead to some other disturbances to the magnetic sensor as well. We derived the formula of the residual magnetic moment and the formula of the induced magnetic moment of ferromagnet. Based on the formulas, a method for real-time magnetic compensation is designed to compensate the ferromagnet's moment. Then an experiment is performed for verification. The result has showed that it can compensate > 90% of disturbances. (C) 2012 Elsevier B.V. All rights reserved.
