Show the Direction of Magnetic Field Lines
Magnetic fields are invisible. You can’t see them, but you can see what they do, like attract a paper clip or push another magnet away. But wouldn’t it be cool if we could find out how to show the direction of magnetic field lines? This activity will help you do just that. You'll even find out how to preserve your images of magnetic fields: for a science fair project, or your own mag-nificent art.
What do different magnetic fields look like?
