I needed a magnet that would hold the turntables in place on an English class game board. The magnetic vinyl strips available at any hardware store were too weak for the job. I found these magnets through a web search and found them to be just the right size and strength. Two of them are 1/16" thick and 3/16" in diameter, perfect for the design I already designed, and they were strong enough that their box had 1/16" holes in the sheet metal in the panels I'm very happy with the result.
