Current explanation

  1. Mar 3, 2005 #1
    Is there a definition for the word electricity which will explain why spinning a magnet around a wire will produce a current?

    Faraday's law explains the second part.While the definition of a current or "electricity' is pretty useless here.

    Electricity: The motion of electrical charge (called "current" in physics)

    Magnetic Field: The type of field produced by a charge in motion.

    Magnetic field is just our name for the way electric fields change due to relative motion. The fact that a bar magnet can induce a current would seem much more natural if your eyes could see the the microscopic currents going on in the bar magnet.

    A charge in arbitrary motion produces an electromagnetic field.U may check the Lenard-Wiechert potentials...And compute the fields (:devil:)

    That's bs.Magnetostatics exists very well,independently of any electric field/potential...
