Demonstration, Eddy Current Experiment

The Eddy Current Experiment demonstrates Lenz's Law.

  • Copper Tube Features End Caps for Self-Contained Storage
  • Copper Tube Length: 33 cm
  • Neodymium Creates Electrical Current that Resists Falling
  • Experiment Demonstrates Lenz's Law
Two test masses are sent through a 33 cm copper tube. One mass drops quickly, but the other seems to defy gravity by slowing as it falls.

It does this because one mass is steel, and the other is neodymium, a magnet that creates a moving magnetic field, which produces an electrical (eddy) current that resists its fall.
