In their case it is a completely common physical phenomenon - passage of current through conductor, through which flow in top tens to hundreds thousands of amperes, and produces in their vicinity electromagnetic fields, incredibly strong.
Katika kesi yao ni ya kawaida kabisa kimwili uzushi - kifungu cha sasa kwa njia ya kondakta, ambayo kati yake kupitia katika kilele makumi mamia Maelfu ya amperes, na hutoa katika maeneo ya jirani mashamba electromagnetic yao, incredibly nguvu.
