Magnetic Levitation cradle
Lifts a magnet from below

circuit boards.  The row of hall-effect sensors is visible on the boards.]


Based upon an electrically-produced Meissner-like effect

I'm a science hobbyist and occasional exhibit designer for science museums. The devices shown here were part of a prototype "room-temperature superconductive table" which never made it to a museum. I thought I'd place it here so students and hobbyists could experiment with this strange maglev effect.

This device is not trivial to build, so I would recommend it mostly for ADVANCED HIGH-SCHOOL LEVEL AND ABOVE. If you've never built any electronic devices before, I wouldn't recommend the maglev cradle as your first project. I built mine using parts from a mail-order surplus store. Since you'll be using DIFFERENT surplus parts, my plans are only guidelines for experienced hobbyists rather than detailed instructions for a beginner. Experimentation will be required in order to get this device to work. Also check out "Simple maglev train", which uses only permanent magnets, and the Science Projects page. Dowling magnetics sells SDK-100, a maglev train kit which uses only permanent magnets. DON'T MISS MY "AMATEUR SCIENCE" WEBSITE
