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.

Powerful.

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.
