We can produce the NdFeB ring magnets in different sizes, different grades (strengths and temperature ratings), 
different coatings and in axial or diametric magnetization. 
There exits two styles "pure" rings and "countersunk" rings. The holes are centrally located. The countersunk ring allows
for the magnet to be screwed onto another item.
Due to their shape, the ring magnets have a higher permeance coefficient than the same size disc magnet. 
This means they can resist demagnetization better, making them ideal for repulsive applications.
