النيوديميوم المغناطيس الدائري هي مثل أقراص أو اسطوانات, ولكن مع وجود ثقب الوسط. Most neodymium ring magnets and tube-shaped magnets are axially magnetised: تقع شمال وجنوب القطبين على السطوح دائرية مسطحة (“فوق وتحت”). The few diametrically magnetised neodymium ring magnets with poles “يسار و يمين” يتم وضع علامة على وجه التحديد.

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.
