Our 20mm diameter Neodymium cylindrical rod magnet produces an astonishing 15kg pull for a relatively small and affordable magnet. They have many uses in engineering, manufacturing and technology where small size and maximum strength are required. What's more, because of their resistance to demagnetisation they are ideal for creating a shock-absorbing or damping effect when used to repel other magnets. These magnets come with a safe-handling warning; because they are so powerful they can be dangerous if not handled carefully.
