These Neodymium (NdFeB) circular disc magnets with a black epoxy finish and astonishing pull strength of 17kg, are extremely effective for a relatively small magnet. The black epoxy finish helps to protect the magnet from corrosion in instances where the magnet may meet water or other hazardous conditions. These magnets are ideal for when maximum strength is required in limited space and are popular within the engineering and manufacturing industries. 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.
