Abstract
The present invention provides device for generating magnetic field of calibration and built-in self-calibration (BISC) magnetic sensor and calibration method, in which a novelty structure utilized for generating a uniform, predetermined magnitude, and three-dimensional orthogonal or approximately orthogonal magnetic field of calibration is arranged in the magnetic sensor such that the magnetic sensor can perform BISC function for obtaining a calibrating information with respect to the magnetic field of calibration anytime and anywhere. The magnetic sensor can be arranged in the application device for measuring magnetic field under the real environment where the magnetic sensor is located and the calibrating information are utilized for calibrating the measuring result thereby improving and advancing the accuracy of measuring three-dimensional magnetic field.
