These magnets have a central hole for mounting on shafts. Use them in motors and turbine generators. Alnico magnets aren't as strong as rare earth magnets, but they withstand the highest temperatures. Magnets come with a keeper that covers the poles to preserve the strength of the magnet and protect it from attracting metal during storage.
