Neodymium Diametrically Magnetised

Diametrically magnetised magnets, as the name would suggest, are magnetised through the diameter of their ring, disc or cylindrical shape. Frenergy has round-shaped Neodymium magnets with this type of magnetisation in a range of magnetic grades, some of which are highly resistant to heat. Most diametric magnets are used to produce rotational movement in devices such as electric motors, sensors and wind turbines. Rotational movement from diametrically poled magnets can be used to switch open, then close an electrical circuit inside a Reed Switch. These magnets are also used to produce a rotating field that alternates from North to South and can operate sensors and flow meters that measure fluid volumes passing through a pipe. Most stock Neodymium magnets are, in fact, Axially magnetised with the North and South poles on the large, flat surface areas and therefore have strong holding ability. Conversely, magnets with diametric magnetism have the poles on curved surfaces and are not suited to holding applications.
