To measure the magnetic field, an alternating current (AC) is passed through the drive coil, causing the core to undergo cyclic magnetization and demagnetization. This cyclic process generates a secondary magnetic field that follows the external magnetic field variations. The sense coil then detects this secondary field and produces an output voltage proportional to the external magnetic field strength.
