About Ferrite Magnet

Ferrite, also known as ceramic magnets, are made of a composite of Iron oxide and barium carbonate (BaCO3) or strontium carbonate (SrCO3). Widely available since the 1950's, this material is commonly available and at a lower cost than other types of materials used in permanent magnets. Ceramic magnets are made using pressing and sintering. Sintered magnets are a type of ceramic composed of the compressed powder of the alloy material being used. Sintering involves the compaction of fine alloy powder in a dry and then fusing the powder into a solid material with heat. While the sintered magnets are solid, their physical properties are more similar to a ceramic and are easily brokenand chipped.

Ferrite magnets are brittle and hard generally requiring diamond wheels to grind and shape.

These magnets come in a number of different grades. Ceramic1 is an isotropic grade with equal magnetic properties in all directions. Ceramic grades 5 and 8 are anisotropic grades. Anisotropic magnets are magnetized in the direction of pressing. The anisotropic method delivers the highest energy product among ceramic magnets at values up to 3.5 MGOe ( Mega Gauss Oersted). Ceramic magnets have a good balance of magnetic strength, resistance to demagnetizing and economy. They are the most widely used magnets today.

Beneficial characteristics of ceramic magnets include their low cost, high coercive force, resistance to corrosion, and high heat tolerance. Drawbacks include their low energy product or "strength", low mechanical strength, and the ferrite powder on the surface of the material which can rub of and cause soiling.

Pot Magnet

This Neodymium or ferrite ring magnet in a steel pot is countersunk. It can be fastened with a countersunk screw. The steel pot substantially increases the holding of the magnet, but requires full contact with the opposing part, e. g. A steel plate. Magnets in steel pots don't have much effect into the distance, i. e. They are not suitable to attract item from a distance, but they are very well suited to hold on to a pieceof metal in full contact.
