ABSTRACT:
Intensities of electric and magnetic fields are measured by locating a conductor and reference conductor in the electromagnetic field so the conductor and reference conductor simultaneously output plural currents that are respectively simultaneously measured in different directions relative to the electromagnetic field. On the basis of the magnitudes of the currents and the phase difference, an electric field component current generated in the conductor by an electric field included in each current and a magnetic field component current generated in the conductor by a magnetic field included in each output current is calculated. On the basis of the magnitudes of the calculated electric field component current and the magnetic field component current, the electric field and magnetic field intensities are measured.
