This ferrite block magnet has a 150mm length, a 15mm width and a height of 15mm.
Hard Ferrite ceramic magnets were developed in the 60’s and today comprise 75% of world magnetic consumption. Despite their relatively low magnetic values, they are the most popular magnet on the market due to ready availability and relatively low cost. The Most Cost-Effective High Resistance Permanent Ferrite Magnets
The raw material from which ferrite magnets are produced is Strontium Ferrite powder (mainly ScO.6Fe203) which is formed in a press while subjected to an electric field. This process allows the direction of the magnetic field to be determined during the production of the magnet. Low Cost Permanent Block Bar Ceramic Magnets

Ceramic blocks (sometimes called Ferrite block) are available in several different sizes. Ceramic/Ferrite magnets are a low cost but versatile and multipurpose type of magnet. Large ceramic block magnets are often used in sweeping and separation applications. Smaller ferrite blocks are commonly used in motors. Any machining of ferrite blocks must be done with a diamond wheel, ideally before magnetization, as they are hard and brittle. These are medium strength magnets.
