Broadband Tri-Axis Magnetic Field Measurement System

E. Lunca, V. David, A. Salceanu

Abstract

The interaction effects between electromagnetic fields and biological tissues depend on the frequency range of the exposure fields. The measurement of low-frequency magnetic fields with regard to human exposure typically requires two field meters, one working in the frequency bandwidth from 20 Hz to 2 kHz and the other working from 2 kHz to a few hundred kHz. This is why the authors propose a tri-axis measurement system which covers alone the wide frequency range from 40 Hz to 150 kHz. It can be used for both spot measurements and long term monitoring of the magnetic field especially inside the residential buildings.
