Marbles, Inertia, and Paper Plates


This experiment started out as a Science Photo Challenge and got such a great response that I wanted you to experiment with it yourself. It is a wonderful physic puzzle, and offers interesting insights into the science of force and motion.

To try this, you will need:

  • a paper plate
  • scissors
  • a marble or other small ball

Lets start with the question from the Science Photo.

Magnetic Lines?

Open any book or web page that talks about magnets, and you will probably see a drawing that shows magnetic lines of force that extend from one end of the magnet to the other.

Are there really lines of magnetic force as they show in the drawings? Well, lets find out.
