This paper derives various common arrangements of power lines that produce intense magnetic fields to assess magnetic field exposure accurately. The sources of the extremely low frequency (ELF) electric and magnetic fields, and the asymmetric distribution in the magnetic coupling problem associated with multi-conductors in three-phase systems are discussed. Theoretical simulatin (using the MATLAB software package) and on-site testing are used to investigate interference from power distribution lines with the electromagnetic force (EMF) of devices. Finally, some strategies for attenuating the high magnetic field intensity and mitigating the electromagnetic coupling problem are proposed.
