Fascinating project propels aluminum rings to a considerable velocity. Demonstrates the LORENTZ force plus important properties of magnetic energy. Includes 2 aluminum rings (you may cut more from the appropriate-sized aluminum tubing, and we also sell additional rings cut and deburred). Rings may be restrained to flyway for safety or classroom demonstration. Adult supervision usually not required for outside use. Operates from 8AA batteries that slide into hand grip. Can be easily modified to propel ball bearings.
