Each magnet's north and south pole are on opposite 40mm diameter faces
Each magnet can support a steel weight of up to 35.94lbs 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 reduce corrosion and provide a smooth finish
These 40mm diameter large Neodymium disc magnets produce an astonishing pull of 35.94lbs and every magnet has a triple coating of nickel, copper and nickel again to prevent against corrosion. Our Neodymium disc 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 compact 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.
We used your magnets in a prototype for a new exhibit. The magnetic field of the magnet was used to trigger hall effect sensors. This meant that strong high quality magnets were essential. I have purchased from First 4 magnets before.

I am amazed at how strong magnets are
excellent service and fantastic packaging on both occasions that I have dealt with you, I use 14kg pull magnets for building radio control model aircraft. I am amazed at how strong magnets are.
