Ferrite (Ceramic) Magnets
Ferrite magnets are part of the Permanent Magnet family and are probably the most widely used type of Permanent magnet across the world. They contain Ceramic magnetic material which, unlike their Rare Earth magnet cousins, have few conductive properties. This means Ferrite cylinder magnets are especially well-suited to use as EMI suppression magnets for many electronic audio devices and computers.

Ferrite (Ceramic) Magnets
Ferrite magnets usually become the magnetic component inside mechanically operated metal detection devices or in metal recovery and storage tools. These devices and tools utilise the inherently wide and deeply penetrating magnetic field that is associated with Ferrite magnets to collect and retrieve metal waste and metal contaminants from large-scale manufacturing processes. The wide and penetrating magnetic field means they are also suited to holding, lifting, and clamping purposes in steel production and metal fabrication plants. Typical Ferrite magnets for sale can include the usual magnet shapes of Discs, Blocks, Rings, and Cylinders. Protective coatings and coverings on Ferrite magnets can include rubber, steel, plastic, and painted surfaces.

Ferrite Magnet Applications and Uses
The range and number of applications that use Ferrite Magnets are vast and varied. Ferrite Ring shaped magnets are well known for their traditional use in loudspeakers and audio equipment. Small Ferrite Ring magnets are very inexpensive and the ring shape makes them easy to attach with a cable tie or similar to another object or surface in order to make it magnetic. The affordable and widely available nature of Ceramic magnets means they are hugely popular with hobbyists, tradespeople, and even amateur inventors who want to create a lightweight or temporary bond with steel surfaces. For a more permanent holding application, epoxy glue can be used to hold the magnet in position.
Ferrite magnets may not be the strongest magnets available but are ideal for the holding requirements of model making and crafts. Lower strength Ferrite magnets are also more suitable for educational situations where students may be unfamiliar with magnetism and need to learn about its power and limitations in a safer, more user-friendly environment. Small Ferrite Disc-shaped magnets can add a simple and quirky magnetic dimension to artistic creations or promotional products, while large Ceramic blocks can have enough power to be used for industrial lifting and commercial holding needs.
Ferrite magnets are ideal for outdoor use and resist corrosion well, so if a magnetic bond is needed on the farm, campsite, or outdoor recreation area, Ferrite magnets are proven to be extremely durable in harsh environments and adverse weather conditions.

Ferrite Magnetic Properties
For many reasons, Ferrite magnets are among the most widely used types of magnets in the world. They are versatile and readily available to purchase in most countries. The Ceramic nature of Ferrite magnetic material makes these magnets hard but also brittle and for many applications, the magnet needs to be fitted with a mild steel casing on the outward-facing sides to protect the fragile magnet from impact damage. The steel case also deflects more magnetic field to the exposed base which increases the overall strength of the magnet. These encased magnets are known as Pot or Channel magnets depending on whether they are Disc or Block shaped.
Despite being one of the first to be commercially developed and one of the weakest in terms of magnetic hold, Ferrite magnets have one of the best heat tolerances of any magnet. Many other types of Permanent magnets lose their magnetic strength either partially or completely when the operating temperature of the magnet exceeds 80℃. Ferrite magnets are able to remain stable and reliable in industrial environments where temperatures can reach 250℃.
Ferrite magnets also have a natural resistance to corrosion and in most cases outperform the more powerful and much more expensive Neodymium magnets. Salty marine environments can be detrimental to any magnetic material but the highly corrosion-resistant Ferrite magnets can withstand long periods of exposure to these harsh conditions with very little or no impact on their performance. Not least of the reasons for the worldwide popularity of Ferrite magnets is their low purchase price. Ferrite Raw materials are not too difficult to procure and the manufacturing process is not expensive. This, in turn, leads to low and stable pricing.

FAQWhat are Ferrite magnets used for?
Ferrite magnets are also known as Ceramic magnets and can be combined with a rubber medium to create the common Fridge magnet advertising material that often arrives in your letterbox to promote local trades and services. Larger hard Ferrite magnets are permanent magnets and can be used for heavy lifting, metal decontamination, sound recording equipment, electric motors, meters, and security sensors.
Are Ferrite magnets strong?
Larger Ferrite magnets can be very strong. A Ferrite block-shaped magnet with 150x100x25.4 mm dimensions can support weights up to 15kg! Ferrite magnets also have a wide and far-reaching magnetic field in comparison to other magnets, which is especially useful for metal detection and retrieval applications.
Which is better, Ferrite or Neodymium?
Each of these Permanent magnetic materials has characteristics that are suited to particular applications. Neodymium magnets produce far greater magnetic energy for their size and are generally much stronger (x7) than Ferrite products. Neodymium magnets are suited to small-sized consumer products where powerful components are required to occupy small, enclosed spaces. Ferrite magnets have less magnetic strength but are very economical and much more resistant to moisture and corrosion. Ferrite magnets are ideal for outdoor applications.
