Diamagnetic Levitation Using Bismuth and Magnets

thingiverse

This project employs two bismuth plates and a large magnet to achieve the levitation of another magnet. Bismuth, being element number 83 on the periodic table, exhibits distinctive properties. It produces stunning crystal formations and displays diamagnetism. For this project, we leverage bismuth's diamagnetic property. 1. Conduct this project under adult supervision due to potential hazards. 2. Note that some STL files deviate from images, but they are easier to use and provide a better visual outcome. 3. Enhanced images will be uploaded shortly to demonstrate assembly and functionality. Print Settings Printer Brand: Up! Printer: Up Mini Rafts: Irrelevant Supports: None Required Resolution: 0.3mm Recommended Infill: Any except None Notes: For optimal results, utilize a lower resolution as the middle and top components will slide excessively without sufficient surface roughness. My Design Inspiration This project draws from principles illustrated in this video. Requirements What You Need One pound of pure bismuth Two neodymium magnets: a. One large to secure atop the piece. b. One small to place between bismuth plates for levitation. Two soda cans – Their bottoms will be molded with molten bismuth. Steel pot – Any unused, as it may become inoperable due to bismuth melting. Stove Hot glue gun Super glue Instructions For this project, flip the soda cans upside down and have a steel pan nearby to catch any potential spills from molten bismuth. Next, melt the bismuth in a stove within the steel pot. Once the bismuth has melted, slowly pour it into the soda can bottoms. Wait for them to cool before carefully removing them. Then, smooth out the ends with sandpaper and polish if desired. Now, print all the required pieces and follow the provided pictures to assemble the components. Subsequently, apply hot glue to secure the bismuth plates within their corresponding indents while keeping both as flat as possible. Lastly, reference the assembly guide images again. Make any necessary adjustments to ensure the middle and top sections hold the magnet in place for levitation purposes.
