20mm O.D. x 6mm I.D. x 20mm thick Diametrically Magnetised N42 Neodymium Magnet ( Pack of 1 )
20mm O.D. x 6mm I.D. x 20mm thick Diametrically Magnetised N42 Neodymium Magnet ( Pack of 1 )

High-performance, diametrically magnetised Neodymium (N42) cylindrical disc magnet with central 6mm hole. These diametrically magnetised magnets have their north and south pole on opposite curved sides, cutting the flat surface in half.

  • 20mm diameter x 20mm thick with 6mm central hole
  • Each magnet's north and south pole are on opposite curved sides
  • Excellent resistance to demagnetisation
  • Coated with three layers of nickel, copper and nickel to reduce corrosion and provide a smooth 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.

5Powerful.

I use these magnets on drive shafts, at 6.1 Tesla they are very powerful. Using only 6 watts as input i can achieve 30,000 RPM.
