Household Appliance Magnetic Field Survey

The results of a non-comprehensive survey of the 60-Hz magnetic fields produced by common household appliances and tools are reported. Maximum magnetic field levels as a function of distance for about 100 different appliances of 25 basic types are characterized by measurement and presented in graphical form. The measurements represent the highest magnetic fields generated by the appliances in any normally accessible direction from them. All sets of measurements but two were made at the fundamental powerline frequency of 60 Hz and all represent narrowband rms levels of magnetic flux density expressed in UT. Measurements at powerline harmonic and other frequencies were not made. The data presented should be useful in understanding the levels of magnetic field produced by household appliances, and also in estimating magnetic-field exposures in homes and workplaces.
