These thin rectangular Neodymium magnets are axially magnetised between the two 107mm x 12.7mm rectangular faces and provide a maximum pull of 15kg. This blocks are made in grade N35 material. Every magnet has a triple coating of nickel, copper and nickel again to prevent against corrosion. Our Neodymium magnets have many creative uses including model-making, theatre design, furniture making, exhibitions, retail displays and packaging. They also have many uses in engineering and manufacturing 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.
