Experiment with pushing around the magnets and see if you can create a 'moving magnet train'. Line magnets up so south sides meet south and north sides meet north. Push the back magnet and watch all the other magnets leap forward. See how many magnets you can get to push other magnets.
Floating Magnet Trick
For this trick, you will need 5 to 8 donut shaped magnets (magnets with a hole in the center and one wooden rod small enough to fit through the magnet, it is preferable if it has a base to it so it can stand up, also made of wood.
First, you need to determine the magnetic forces of the donut magnets and which side is north or south. Remember, polar opposites attract.
For this experiment, you'll want to put three or four magnets along the wooden rod. The placement of the magnets is important. Place all of the magnets with south at the bottom, so when you layer the magnets, the north part of the bottom magnet will attract the south magnet you place on top of it, and the very top of the pile will have a north magnet.
Next, with the next magnet, place the magnet using the north end down. You won't be able to attract it to the north below, so it will continue to 'hover' over the magnets.
You can continue the hovering by placing another magnet on top but make sure the new magnet is south side down. This new magnet will also hover.
Flying Paperclips
This simple trick requires one magnet attached to something like a metal bracket, hanging over a table or tall surface. It also requires one paperclip tied to a piece of string.
Bring the paperclip toward the magnet. The attraction will make the paperclip stick to the magnet.
Measure how far away the clip has to be before the magnet loses its effect by pulling the paperclip away from the magnet using the string.
Bonus: Keep the paperclip flying tying off the string just long enough for the paper clip to 'fly' and not quite reach the magnet.
For an added experiment, hang paper clips off of each other off of the magnet. The magnetic field can have paperclips connect to each other. So see how many paper clips can hang in a line off of the magnet before they are out of range of the magnet and fall off.
