Neodymium vs Ferrite Magnets
Both Ferrite and Neodymium magnets are permanent magnets but each has distinct advantages depending on which type of application the magnet is used for. The environment in which the magnet will operate and the total magnetic field strength required should also be considered. The most obvious difference between the two types of magnetic materials is the overall field strength. This strength is also known as pull force and is usually measured in Gauss or Tesla units. Neodymium magnets can usually produce a magnetic field that can bond to steel with a 7 times stronger adhesive force than a Ferrite magnet of the same dimensions.
Below are notable differences between the two types of magnetic materials. These typical characteristics can make either of the magnetic materials the most suitable selection for a particular application.
Advantages of Neodymium magnets:
- Unrivalled magnetic energy output. Neodymium magnets are constructed from the strongest rare earth magnetic material in the world and can produce a magnetic bond that is 7 times stronger than Ferrite/Ceramic type magnets.
- Highly resistant to demagnetisation. Neodymium will maintain its magnetic properties, even under extreme conditions and environments.
- The superior strength of Neodymium means smaller or thinner magnets can be substituted to reduce the overall footprint of an appliance, device or apparatus.
- Neodymium magnets are relatively quite durable and able to tolerate moderate collision impact and abrasive forces. Neodymium Pot magnets are designed for industrial applications and have a steel covering to further increase durability.
- Moderate conductive properties.
Advantages of Ferrite magnets:
- Lightweight magnetic material. Ferrite magnetic material does not have excessive weight to consider in applications where this is important.
- Highly corrosion resistant. Where harsh outdoor or marine environments are encountered, Ferrite magnets can offer long-term durability.
- High-temperature resistance. Ferrite material can operate in temperatures up to 250℃ and still retain their magnetic and structural integrity.
- Low-cost option. Ferrite products are relatively inexpensive and ideal for home-based or artistic projects.
- Low magnetic strength. Ferrite magnets are easily handled and suited to use where excessive magnetic strength can make the removal and relocation of a magnet difficult.
- Low conductivity
