Most ring magnets and tube-shaped magnets 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 specifically marked.
If you are 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.
With diametrically magnetised ring magnets you can build sculptures. You can also combine them with other shapes, such as neodymium rod magnets.

Screwing on ring magnets
It seems tempting to screw on ring magnets due to their shape (magnet with a hole) and the low price. We advise against it, however, since the material is very brittle and chips easily. It is better to use screw-on magnets or pot magnets with countersunk borehole.
