The cylindrical and round shaped ceramic magnets are not called as ceramic cylinder(rod) magnets,they are not as strong as neodymium magnet rod, but they are less expensive hand have excellent resistance to demagnetization.

Ceramic Cylinder Magnets Are Sometimes Preferred Over Neodymium Cylinder Magnets

Although ferrite(ceramic)cylinder/rod magnets are rather brittle,they possess good resistance to corrosion and can be used in high temperatures. When looking for a cost effective alternative with good demagnetization resistance, the ceramic cylinder magnets are preferred over neodymium cylinder magnets. Cylindrical ferrite(ceramic) magnets are used in motors, water conditioning and reed switches. Ceramic /ferrite magnets suppress high frequency noise in electronic circuits. This makes them ideal for 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.
