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!

Features:

  • Ceramic magnet constructed of strontium ferrite
  • Fun pencil experiment
  • Useful for demonstrations and science projects
  • 3/8" inside hole diameter

 

This magnet has a strength of: 450 Gauss (0.045 T)

Customer Reviews


5 star rating  Magnet Repulsion Demonstrator
William Hinton from USA, New Hampshire
I used to buy these from Home Depot but they stopped carrying them. I do education outreach for elementary students regarding magnet theory. I have wooden blocks with 3.8-inch dowels that allow the magnets to float in repulsion. I make these in my shop and donate them to teachers after the events with their students. I now have an endless supply of parts for many more demonstrators. Thanks
