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! THX!!!
