Round Circle Disc Magnet Ø 8 mm, height 2 mm Ferrite Y30 no coating – holds 150g
Disc magnets have a diameter greater than thickness, and are available in different sizes. For Ferrite magnets in a cylindrical shape, see our Rods section. These round disc magnets can be easily affixed into drilled holes. The dimensions for disc magnets are measured “Diameter x Height”. The discs are magnetised from top-to-bottom through the thickness.
Ferrite (Ceramic) magnet is manufactured from oxide materials using powder metallurgical process. ferrite magnet is most widely used because of its low cost, high-energy, good electric insulation and excellent resistance to demagnetization. The most common type of hard ferrite magnet is anisotropic strontium, anisotropic barium and isotropic barium magnet.
Ferrite (Ceramic) magnet has the following advantages: high coercive force, high electric resistance, long-time stability, and economical price. Phyiscal Therapy Round Circle Ferrite Magnets Y35
Ferrite magnets can be used in a wide range of applications due to their high coercivity and low cost. They also have good machining properties which allows them to be cut into different shapes and sizes – they are cut with diamond tooling; standard drills and wire spark erosion techniques do not work. Ferrite has an excellent resistance to demagnetisation/corrosion, however care must be taken when handling the product due to its brittleness. Ferrite magnets can be used up to +250 degrees C making it ideal for use in electrical machines. At sub-zero temperatures e.g. less than -10 to -20 deg C, ferrite may start to show a reduced pull force (the temperature and the degree of weakening depends on the magnet shape and is application specific; for most uses this effect does not happen as the magnets never get that cold).

Applications of ferrite magnets
The ferrite magnets lend themselves to a variety of applications: from simple, such as magnetic locks for furniture or leather, magnetic lifters or magnetic separators, to the most sophisticated electric micromotors, which represent, along with speakers and some special magnetic applications, the areas of interest.
