Coated with a triple-layer nickel-copper-nickel finish, these magnets resist corrosion while delivering reliable performance in motors, magnetic racks, and reed switch setups. Engineered with tight tolerances and supplied with safety documentation, they are ideal for professionals seeking compact, high-quality magnetic solutions. ## Description Product Description Pack of 106mm outer diameter x 3mm inner diameter x 1mm thick+/-0.1mm toleranceEach magnet's north and south pole are on opposite curved sidesExcellent resistance to demagnetisationCoated with three layers of nickel, copper and nickel to reduce corrosion and provide a smooth and clean finishUnusually, 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. Within motors, diametrically magnetised magnets are commonly 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. Set Contains: 10 x 6mm O.D. x 3mm I.D. x 1mm thick magnet(s) Review: Occhio al titolo!
