Requirements for power line magnetic field mitigation using a passive loop conductor
IT IS required to develop mitigation techniques to address the biological effects of an ELF (extremely low frequency) mag- netic field generated from power facilities. Concerning the over- head AC power lines, the application of shielding materials is unrealistic because distances between phase conductors are too large.

Editorial: “It's déjà vu all over again”
Another occurs when researchers forget that ELF magnetic field coils may produce heat. Because most cell culture incubators use AC electric heaters to maintain a high internal temperature, but cannot extract heat to keep temperature from climbing too high, a heat-generating magnet coil can alter the local temperature inside an incubator or magnetic shield .
