Drop two metal plugs through a copper tube, one at a time. One falls slowly; one falls quickly. With one copper pipe whole and one with a viewing slit, use as a discrepant event. After students learn the principle of Lenz's Law with the solid copper pipe, they are amazed to see it work the same with a slit. In each copper tube the falling magnet sets up an Eddy current whose magnetic field attracts the falling magnet. Each kit includes a copper tube, two test plugs of similar size and mass (one non-magnetic and one magnetic), two end caps for self-contained storage, and instructions. This is one of our favorite demonstrations. Each tube is approx. 1.6 cm (3/4") dia. x 30.5 cm (12").

3-D Magnetic Field Demo

This clear plastic case makes it possible to observe a magnetic field in 3-D, without worrying about the mess of iron filings getting loose!

Eddy Current Tubes (Super-Large)

Large diameter, thick-walled copper and aluminum Eddy Current Tubes. Available in three sizes.

Magnetic Accelerator

Could this be the basis of a perpetual motion machine? Great for open-ended discovery.

Magnetic Field Viewer Card

You can use this amazing viewer card to locate the poles of a magnet. Available separately or as a kit.
