Yes, the Rad Shack rare-earth mags. are exactly the same diameter, but half the height. They come two per package. I don't think it helps to much with centering due to the fact that they would both shift in the clamp together. The magnetism of the r-e mags. is so strong, they lifted my ceramic magnet AND the entire plastic bar almost 6in. off of the table!!! I'm lucky as hell I didn't lose the spring!!!
