About This Product
A non-magnetic slug dropped through the PVC tube falls straight through, while a magnet in the copper tube drifts down slowly at a steady speed as the induced eddy currents push back against it. In the pendulum test the solid aluminium plate stops sharply as it swings past the magnet, while the slotted plate keeps swinging, showing how breaking up the current loops weakens the braking predicted by Lenz’s law. Educational Instrument can dispatch the Eddy Current Apparatus STEM Lab to laboratories in Gambia, Paraguay, Malaysia, Australia, Armenia and Togo.
Frequently Asked Questions
What is the PVC tube for in the Eddy Current Apparatus STEM Lab?
It is a non-conducting control: no eddy currents form in PVC, so a falling slug drops freely and can be timed against the slow fall of the magnet in the copper tube.
