Static build up and magnetism!

  1. Sep 24, 2010 #1
    What is the difference between static attraction or repelling, compared to magnetic.
    I understand the princips of static build up and why a charged positive and charged negative attract each other. I also understand how the atoms are arranged in a "metal-magnet".
    But why cant you attract a static object (baloon) wit a magnet?

    Moving electric charges create magnetic fields and moving magnets create electric fields, but they don't directly interact with each other like that. A magnetic field does not interact with an electric field directly. The electric field has to be moving, thereby creating its own magnetic field, and then those two magnetic fields can interact (or vice versa with magnets and electric fields).

    Okay, that would explain electromagnetism!
    So a static field consists of "non moving" electrons! And a magnet consists of molecules with moving electrons, is that right/the answer to why they wont interact?

    The balloon has an electric field but no magnetic field. The magnet has a magnetic field but no electric field. Therefore, there is no force between them.
