How can you make a magnet float in mid-air?
Push a pencil or straw through the hole in your two ring magnets until they come together, or attract. Now remove the top magnet, flip it over, and slide it back over the pencil. It will magically float above (or repel from) the other magnet.
Try to add a third or fourth magnet. How many can you float? Now slowly push the bottom magnet off the pencil. Did the magnet “jump”?
All magnets have a north and south (or positive and negative) pole. Opposite poles attract each other, and like poles repel.
