The cylindrical and round-shaped ceramic magnets are not identified as ceramic cylinder (rod) magnets. While they may not possess the same magnetic strength as neodymium magnet rods, they are a more cost-effective option and exhibit excellent resilience against demagnetization.

Ceramic Cylinder Magnets Are Sometimes Preferred Over Neodymium Cylinder Magnets

Ceramic (ferrite) cylinder/rod magnets, despite being relatively brittle, offer excellent resistance to corrosion and are capable of functioning in high-temperature environments. When affordability and strong demagnetization resistance are a key consideration, cylindrical magnets are a preferred alternative to neodymium cylinder magnets. Cylindrical ferrite (ceramic) magnets are utilized in various applications such as motors, water conditioning, and reed switches. In electronic circuits, ceramic/ferrite magnets suppress high-frequency noise, making them ideal for use in speakers and car audio systems.

Disadvantages of Ferrite (Ceramic) Cylinder/Rod Magnets

  • Not as strong as rare Earth neodymium magnets – typically offering around 1/7th the pull force of similarly sized neodymium magnets

  • Custom shapes can carry mould charges

  • When taken to around -20 degrees C (-4F) and colder, the Intrinsic Coercivity (Hci) falls to a level that risks the magnet possibly starting to demagnetise (depending on the shape and the application)

  • Ceramic Cylinder magnets are used in applications that involve a magnetic field with a longer field reach, including sensors, speakers, consumer products, consumer electronics, read switches and meters.

Advantages of Ferrite (Ceramic) Cylinder/Rod Magnets

  • Do not corrode in water

  • Can be used up to +250 degrees C (482F)

  • Sometimes up to +300 degrees C (572F) in special circumstances

  • High coercivity (Hci) that increases as magnet heats up

  • Electrically insulating

  • Relatively low cost - good for cost saving projects
