Newton’s Nightmare

Principle Demonstrated: Lenz’s Law

Safety Considerations

            Don’t let the magnet hit a bare table. They will chip. Put a fluffy towel on the table top.


This is a simple magic trick. It works every time because of physics. See the video below to see how to present the trick. I do this at the beginning of the unit on magnetism. At the end of the unit I ask them how the trick worked.


Newton’s Nightmare magic trick from ($15)


What it demonstrates:

As the magnet descends through the tube counter magnetic fields are setup. The fields slow the magnet’s descent.
