Introduction to power-frequency electric and magnetic fields. [PDF]
Environmental Health Perspectives, 1993 This paper introduces the reader to electric and magnetic fields, particularly those fields produced by electric power systems and other sources using frequencies in the power-frequency range. Electric fields are produced by electric charges; a magnetic field also is produced if these charges are in motion. Electric fields exert forces on other charges;
