field strength

  • field intensity
Electromagnetism. The strength of an electromagnetic field in the far field. The measurement may be either of the electric or the magnetic component or the power flux density of the field and is expressed as V/m, A/m or W/m2, respectively. For measurements made in the near field, the term "electric field strength" or "magnetic field strength" is used according to whether the resultant electric or magnetic field, respectively, is measured.
