As you drop neodymium magnets down these large diameter, thick-walled copper and aluminum tubes, you can watch them twist and turn as they slowly fall. A moving magnetic field creates a surprisingly strong opposing magnetic field in these tubular conductors. Each tube kit listed below contains a thick-walled Eddy Current Tube and sample neodymium magnets. Please see below for details. The length of the heavy-walled aluminum tube is calculated so that magnets take the same time to fall as the shorter copper tube.
