What is Newton's Nightmare?
The demonstration materials consist of a conducting nonmagnetic hollow metal tube, a small weight, and a small weight with a magnet within.
Begin by dropping the nonmagnetic weight through the tube. It should fall through quickly as the force of gravity alone is involved.
Next, the magnetic weight is dropped through the hollow tube. A significant delay occurs as the laws of electricity and magnetism
slow the weight's descent through the tube.
