strontium ferrite bar magnet
Ferrite (magnet) - Wikipedia
A ferrite is a ceramic material made by mixing and firing iron(III) oxide (Fe2O3, rust) with one or more additional metallic elements, such as strontium, barium, manganese, nickel, and zinc. They are ferrimagnetic, meaning they are attracted by magnetic fields and can be magnetized to become permanent magnets. Unlike other ferromagnetic materials, most ferrites are not electrically conductive, maki

Strontium Ferrite (SrO.6Fe2O3) magnets and Barium Ferrite (BaO.6Fe2O3) magnets are the two types of ceramic Ferrite magnet. The Strontium Ferrite magnets are the most commonly manufactured due to having stronger magnetic properties. The Ferrite magnets (Ceramic magnets) have a characteristic “pencil lead” colour (i.e. a dark grey colour).

Ceramic < Adams Magnetic Products, LLC
Ceramic magnets can be classified into two main types based on coercivity level: hard ceramic magnets and soft ferrite cores. 1. Hard ceramic magnets have a high coercivity level, meaning their magnetic properties are difficult to alter. This quality makes them well-suited for applications that require a high-strength permanent magnet.
