| Abstract(in English) | In this paper, an AC magnetic field standard system for AC magnetometer calibration is described. The target field strength and frequency range are 7.162 A/m (9 μT) and 50-60 Hz, respectively. The system to generate a reference magnetic field is based on the Helmholtz coil formula. In order to improve the uncertainties of the reference magnetic field and magnetometer calibration, we improve the Helmholtz coil formula for AC magnetic fields. Validation is achieved by using two calibration systems based on different principles. |
