Abstract Different techniques for the reduction of thc magnetic field arising from either overhead lines or buried cables are presented, based on the use of active conductors for the compensation. Thc optimal choice of the currents to bc driven in the con~pensation wires is attained by means of a genetic algorithm, which compares favourably ~ i t h deterministic algorithms In terms of accuracy and computational costs. The procedure may be applied to an) kind of source configuration, with appropriate modifications. ensuring significant magnetic field reductions. 1 Introduction Increasing attention is actually devotcd to the magnetic field levcls due to power lines either in the overhead and cable configuration. Various mitigation strategies are available and are generally applied and experienced at the design stage, while the p
