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. They can also be used to produce a magnetic rack and pinion system by using a line of North and South in alternating polarities. It is also possible to use diametrically magnetised magnets for reed switch applications.

Neodymium disc magnets are used in thousands of assemblies and products. These high performance magnets can be easily fixed into position using adhesive or pushed into holes and grooves in wood or plastic. Neodymium disc magnets are commonly found in point of sale display units, stationery folders, scale models and industrial applications. Neodymium disc magnets are truly versatile and are used as widely in homemade arts and crafts as they are in high-end technology and engineering applications. Neodymium magnets attract each other with almost twice the force that they use to attract steel objects. They also attract each other through very large distances, even small magnets will attract each other through the thickness of your finger.
