A friend of mine who is a teacher at a collage wants to demonstrate the magnet energy under the topic of magnetism after our discussion.I suggested him Bedini or Newman design but they are not too easy designs.So I am looking for your suggestions about an easy design to see the overunity potential of magnets.What are your suggestions?
maybe the SMOT?
