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.

Material	Approx. Tube Length	Approx. Fall Time	Included Neodymium Magnets	Item Number
Copper	18 cm (7")	4 sec	2 rings	ED-100
Aluminum	36 cm (15")	4 sec	2 rings	ED-125
Copper	1 meter (39")	24 sec	2 rings	ED-135
