Magnet Man

From site:  This web site is devoted to magnetism and the cool experiments you can do with permanent magnets and electro-magnets.  Some of the experiments are very basic – things you’ve done since second grade.  Others are unique; perhaps you hadn’t thought of doing some of these before, or had difficulty in trying to set them up.  Lists of the materials needed for the demonstrations, directions on how to assemble them, instructions on how to show them, and notes on how they work are all here for you.
