摘要
A novel equivalent circuit model of a magnetic probe is proposed. It not only considers the coupling of the magnetic field under test on the probe output, but also considers the coupling of the environmental electric field on the probe output. The proposed equivalent circuit is verified by numerical and experimental results. A good correlation between the directly simulated/measured probe output and the predicted one is observed. Furthermore, based on the equivalent circuit, a formula is proposed to extract the magnetic and electric fields coupling coefficients. It can be considered as the extension of the available probe calibration method, where only the magnetic coupling coefficient is extracted. All of the examples show the feasibility of the proposed equivalent circuit and calibration formula.
