How charged particle got to do with magnetism

  1. May 3, 2010 #1
    hello, I am not too sure of how charged particle got to do with magnetism.

    "Magnetism is a force of attraction or replusion that acts at a distance. It is due to a magnetic field, which is caused by moving electrically charged particles or is inherent in magnetic objects such as a magnet." (form http://www.school-for-champions.com/science/magnetism.htm)
    do charge particles means electron and it is their electron sub shell that causes the effect of magnetism? Is that also why current produces a magnetic field? would like some explanation!

    Re: Magnetism

    your question is kind of hard to answer , at least for me because it is so fundamental.
    But a current carrying wire has an EM field because the charge is moving . your asking
    why moving charges creates magnetism , The electron has an electric field and when this E field changes it creates a magnetic field , I don’t know it this will answer your question . So a changing E field can create a magnetic field.
