This 1.125 inch diameter ceramic ring magnet is made of strontium ferrite. It is a classic low-cost magnet for demonstration and experimentation. Just put several of these ring magnets on a regular pencil and watch as their opposite poles rebel against each other, causing them to levitate. Get a few of these for your next science fair project and you’ll see your grade levitate too!
