20 x 20 x 5mm thick N42 Neodymium Magnet - 7.8kg Pull

• 20mm x 20mm x 5mm thick
• +/-0.1mm tolerance
• Each magnet's north and south pole are on opposite 20mm x 20mm square faces
• Each magnet can support a steel weight of up to 7.8kg vertically from the magnetic face when in flush contact with a mild steel surface
• Excellent resistance to demagnetisation
• Each magnet is coated with three layers of nickel, copper and nickel to improve corrosion resistance and provide a smooth and clean finish

These small neodymium magnets are axially magnetised between the two 20mm x 20mm square and produce an incredible pull of 7.8kg. Each magnet is coated with three layers of nickel, copper and nickel to improve corrosion resistance and provide a smooth and clean finish. Our neodymium magnets are commonly used in creative applications such as model-making, theatre design, furniture making, exhibitions 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.
