NORMAL EMF IN THE HOUSE


The magnetic fields in the house, with the electricity switched off, should be as low as possible and are usually less than the UK average of 0.04 microtelsa (μT). For detached houses set back from the road, the average fields from outside sources is about 0.02 μT. For flats and for terraced houses right up to the pavement have higher fields, however if they are about about 0.1 μT then an external electrical supply fault should be suspected.
