Attenuation of extremely low frequency magnetic fields from appliances

The main reason for magnetic field measurements is to find out what causes disturbances in electrical appliances. Another reason for the increasing amount of measurements is the EMC (electromagnetic compatibility) standard, which sets the magnetic field immunity level for appliances [1]. Besides these technical points of view, possible health effects caused by the power frequency magnetic fields have also been discussed in recent years, and there are already guidelines for exposure to these fields [2, 3].
