Within our stock of 25mm diameter disc magnets you will find incredibly strong neodymium magnets, high operating temperature samarium cobalt magnets and great value ferrite disc magnets, plus non-magnetised steel discs. Many of our magnets are also available as self-adhesive versions available with either pole on the magnetic face. Within our 25mm diameter range you will also find a number of countersunk and pot magnets which are designed to provide the maximum clamping force for the size of the magnet.
