Spherical and Hemispherical Magnets  | | | We had these magnets made primarily to see, first of all, if it was possible and, second, to see if we could find uses for them. As with our other rare-earth magnets, we have quickly found uses for them and expect to find more.
The 1/2" dia. hemispherical magnet (which makes a superb swivel anchor for a mobile) can be used in adjustable arms, specialized hinges, etc. The 5/8" (15mm ) dia. or 1/2" dia. spherical magnet will hold a chain of ball bearings together to provide a near-frictionless rotating suspension mechanism. One can also be rolled along the crack in a hardwood floor, where it will stop and quiver like a Labrador on point whenever it rolls over a nail, so that you can map the nails and then cut into the floor without fear of tool damage.
The gee-whiz factor is very high for both magnets.
