Ring magnets with a difference; these 4mm neodymium ring magnets are manufactured with an outer step on one magnetic face.
These unique 4.3mm (0.17") thick neodymium ring magnets are a recent edition to our range. They are different to regular ring magnets as they are manufactured with a 0.8mm (0.03") deep outer step on one face. They are axially magnetized through their thickness and because they are made from N42 neodymium they have excellent performance for a relatively small magnet.
