Neodymium Ring Magnets are like discs or cylinders, but with a center hole. Most مغناطيس حلقة النيوديميوم and tube-shaped magnets are axially magnetised: North and south poles are located on the flat circular surfaces (“top and bottom”). The few مغناطيسي مغناطيسي neodymium ring magnets with poles “left and right” are specifically marked.

Due to their shape, it is very tempting to screw-mount ring magnets. But please keep in mind, the material is very brittle and chips easily. That is why we advise against the screw-mounting of ring magnets with holes. It is much safer and easier if you use screw-on magnets أو countersunk pot magnets.
