- 4mm diameter x 7mm 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 0.67kg 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
Our 4mm diameter neodymium rod magnets are some of the second smallest in our rod magnet range and produce an astonishing 0.67g 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.
