How do I replicate the Einstein - de Hass Effect experiment? I know the basic premise: hang a slender iron rod inside a ring magnet and it should spin as the electrons all line up, to conserve angular momentum. Are there any websites detailing how to conduct/build/recreate this experiment? I've tried several times to find any and got zilch each time. So I moved on to experimenting. I've tried several ways, including using fishing line (can't make it taut enough to not shift to one side as the line stretches); swivels soldered to the ends of a rod and connected to hooks while the magnet sits on a wooden base (the tension breaks the solder, even JB Weld won't hold, and it's really tough to get an absolutely straight connection across a weld). I've also tried iron magnets and rare earth magnets (use gloves when handling these--there's a safety lesson in there somewhere). Now I'm going to try fixing the rod inside bearings at either end to hold it rigid. The bearings are fixed to a structure and the magnets will sit on a wooden beam midpoint along the rod. Am I barking up the wrong tree?
