- 5mm diameter x 50mm thick
- +/-0.1mm tolerance
- Each magnets north and south pole are on opposite curved sides
- 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
Unusually, diametrically magnetised magnets are not designed to hold the maximum possible weight for the size of the magnet but instead are used to provide rotational movement. A diametrically magnetised magnet is magnetised across its diameter so that the north pole in on one curved side and the south pole is on the opposite curved side. Diametrically magnetised magnets are used on the end of shafts to provide drive.
