It is generally defined as the electrical potential for a source in a circuit.
4 How to Measure EMF In North America, a gauss meter measures the strength of the radiation in the unit milligauss. In other countries, microtesla is used. (1 microtesla = 10 milligauss). Cheaper gauss meters are usually only able to show EMF levels down to about one milligauss (0.1 microtesla).
