Ring magnets neodymium

Most ring magnets and tube-shaped magnets in our online shop are axially magnetised: North and south poles are located on the flat circular surfaces ("top and bottom"). The few diametrically magnetised ring magnets with poles "left and right" are marked with an exclamation mark.
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 or countersunk pot magnets.

If you would like to learn more about the axial and diametral magnetisation of the magnetic rings, you can find detailed information on our FAQ page Magnetisation Direction. Should you be looking for ring magnets that can withstand higher temperatures and are also rust-proof, you will find them in the category ferrite rings.

Applications for neodymium ring magnets

Two ring magnets demonstrate "magnetic levitation" - floating caused by magnetism - in an easy and impressive way. You need two axially magnetised neodymium ring magnets and a pen on which both magnets are pushed together with the same poles. If you hold the pen vertically, the resulting repulsion makes the top magnet float. In the customer project Addicting Table Decoration”, this phenomenon is used in a similar approach. The device built there lets a gold-plated ring float.
With diametrically magnetised ring magnets, you can build sculptures. You can also combine them with other shapes, such as neodymium rod magnets.
Ring magnets with a hole are perfect for use in workshops. If the magnetisation of your screwdriver is weakening, it can be restored with the help of magnetic rings. You can find detailed information on how to do that in the customer project Magnetising a Screwdriver.
If you always misplace your pencil when working in the workshop, a ring magnet with hole can help. Push the end of the pencil through the hole of a suitable ring magnet. Thanks to this magnetic holder, the pencil sticks to ferromagnetic surfaces. How it works is explained in the project Magnetic Pencil.
Some round magnets with holes are suitable for making decorative cords, thanks to their silver or golden alloy. These magnetic cords are used, for example, to tie back curtains. The cord from the project Attaching a privacy screen without drilling”, for example, was embellished with golden magnetic rings.
