N42 Neodymium Disc Magnet - 25mm dia x 5mm thick - 20.5lbs Pull

• 25mm diameter x 5mm thick
• Each magnet's north and south pole are on opposite 25mm diameter faces
• Each magnet can support a steel weight of up to 20.5lbs vertically from the magnetic face when in flush contact with a mild steel surface
• Excellent resistance to demagnetisation
• Coated with three layers of nickel, copper and nickel to improve corrosion resistance and provide a smooth and clean finish

These neodymium disc magnets produce a maximum pull of 20.5lbs, remarkable for a relatively small magnet. Every 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 models and theatre design, furniture making, exhibition stands 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.
