List of SuperMagnetMan's Super Magnet Radial Neodymium Ring Magnets

For the past several years I have had a variety of customers asking for neodymium ring magnets that would be magnetized from the inside to the outside. It seems like a reasonable request except that neodymium magnets, at this time, can only be magnetized in only 1 plane. To create radial magnetization you need to be able to magnetize in straight lines perpendicular to the tangent line at any point on the edge of the outer edge of the ring. That can't be done in neodymium. Of course, as i say that, I know that for the past few months there is a company who can provide these rings. I have discussed this with the actual company that can do it. There is a mold cost of several thousand dollars per size of radial ring that you want and the info I got said that about N35 was the highest grade the process would work with.

I took a different path. For about 2 years I tried to get my manufacturer to make a different type of radial ring - using arc segments like my motor magnets, but mount it in a steel can with all pieces facing with the same pole facing the center.

For several years I have been working with students to improve their ACT scores in Math & Science. Now I have developed some videos to help make the science section easier. Check out my ACT Science Preparation Page
