Ferrite (magnet) - Wikipedia
A ferrite is one of a family of iron oxide -containing magnetic ceramic materials. They are ferrimagnetic, meaning they are attracted by magnetic fields and can be magnetized to become permanent magnets.
Neodymium Magnet vs Ferrite Magnet: Know the Differences
2023年6月12日 · Ferrite magnets, also termed ceramic magnets, are permanent magnets obtained from a composition of iron oxide (Fe2O3) and other elements, commonly strontium or barium. They are named after their main component, ferrite, which is a type of ceramic material.
Ferrite (magnet) - New World Encyclopedia
Ferrites are electrically non-conductive ferrimagnetic ceramics. They are usually mixtures of iron oxides, such as hematite (Fe 2 O 3) or magnetite (Fe 3 O 4), and oxides of other metals. Like most other ceramics, they are hard and brittle.

2023年8月28日 · What is a Ferrite Magnet? A ferrite/ceramic magnet is a permanent magnet type typically derived from the combination of an iron oxide (Fe 3 O 4) and other elements. Such elements utilized in this process include lead, strontium, manganese, cobalt, or barium.
What Are Ferrite Magnets? - Stanford Magnets
2024年4月16日 · Ferrite magnets are permanent magnets mainly made of SrO or BaO and Fe2O3. Compared with other permanent magnets, ferrite magnets are hard and brittle and have lower magnetic energy. However, they are not easy to demagnetize, not easy to be corroded, and their production process is simple, and their price is low.
What Is a Ferrite? - Stanford Magnets
2024年4月16日 · The ferrite is a new type of non-metallic magnetic material developed in the 1940s. It is a metal oxide with ferrimagnetism. In terms of electrical characteristics, the resistivity of ferrite is much larger than that of a single metal or alloy magnetic material, and it also has higher dielectric properties.
