Strategies to Reduce Magnetic Field Exposure
... Distance – separating electrical wiring and people is often effective at reducing magnetic field exposure. The smaller the physical dimensions of the source, the more effective will be any separation that can be achieved. Moving even a metre away from a small transformer may reduce magnetic fields b ...
