    4mm diameter x 8mm thick
    +/-0.1mm tolerance
    Each magnet's north and south pole are on opposite 4mm circular faces
    Each magnet can support a steel weight of up to 0.7kg 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 and clean finish
    Our 4mm diameter Neodymium rod magnets are some of the smallest in our rod magnet range and produce an astonishing 0.7g pull for their size. These particular magnets are favoured among craft enthusiasts and model makers but they also have many uses in engineering, manufacturing and technology 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.
