Magnetic levitation wheel
thingiverse
This is a magnetic levitation wheel. The tip rests on the support, yet the wheel remains suspended without contact with it. It can rotate freely. To make this mobile, you'll need 16 cylindrical magnets, each 6mm in diameter and 3mm thick. You can find them on Amazon here: https://www.amazon.com/Aitsite-Aimants-néodymes-super-puissants-Réfrigérateur/dp/B07D33PG7Y/ref=sr_1_6?ie=UTF8&qid=1545938745&sr=8-6&keywords=magnets Insert the magnets into the base and wheel housings. All base magnets must be oriented in the same direction. The same goes for the wheel magnets, but their orientation must differ from that of the base magnets. This opposing orientation enables repulsion, which results in levitation.
