TERME PRÉFÉRENTIEL

ELECTRIC/MAGNETIC FIELD EXPOSURE  

DÉFINITION

  • The exposure of the magnetic field. An electric field is produced by voltage, which is the pressure used to push the electrons through the wire, much like water being pushed through a pipe. As the voltage increases, the electric field increases in strength. A magnetic field results from the flow of current through wires or electrical devices and increases in strength as the current increases. These two fields together are referred to as electric and magnetic fields, or EMFs.
