About This Product
A magnet dropped through the copper tube sets up eddy currents in the tube wall, which makes this device a demonstration of Lenz's Law. The two slugs look the same, but only the neodymium magnet is slowed by the braking effect, while the plain steel slug drops through quickly. Export orders for the Eddy Current Demonstrator are accepted from Samoa, Australia, Bahrain, Japan, Moldova and Oman.
Frequently Asked Questions
Why does one slug fall slowly?
The slow slug is a strong neodymium magnet, and eddy currents induced in the copper tube wall have a braking effect on it. The other slug is plain steel and falls quickly.
