Aluminum Disk Experiment - Magnet Man

pair of magnets into position so that the aluminum disk is in the gap between the North Hang onto the magnets so they arent pushed away! will slow down to a crawl, and continue spinning, until you remove the magnets. Conclusion: As the aluminum disk spins through the magnetic field, eddy currents


The aluminium disc floats over the mercury and lower end of its spindle rests on an adjustable screw A. The mercury in the chamber reduces the friction of the disc at A and it alio provides path for the current to flow through the disc. For holding the magnets in position, there are two iron bars in the instrument, one above the chamber and other
