Magnets are not to be used as lifting equipment, and they require a freshwater wash after use in seawater.

What Grades of Neodymium Pot Magnet are available?

 

 

There are different grades of neodymium pot magnets, for example N35, N38, N42, N38SH.. etc. Each type of Neodymium magnet is rated according to its material. Magnetic force increases with the magnet's grade (the number following the 'N'). Current high-grade neodymium magnets are N52. Any letter following the grade indicates the magnet's temperature rating. Magnets with no letters following the grade are neodymium standard temperature. So no letter on a standard neodymium magnet indicates its maximum operating temperature, 80⁰ C.

Are Neodymium Pot Magnet Waterproof?
 

Neodymium pot magnets are typically coated with Nickel to prevent rust and corrosion from moisture, but unless coated with a special corrosion resistant coating, they are not waterproof. They should be kept away from water (especially salt water), as exposure to moisture can cause them to corrode and lose their magnetic strength over time. It is important to note that even a small amount of water, such as high humidity, can cause rust to form on the surface of the magnets. If you need to use neodymium pot magnets in a damp or wet environment, it is best to use a magnet with a corrosion resistant coating, or encase them in a waterproof container to protect them from moisture.

How Does Temperature Affect Neodymium Pot Magnet

 

In the application of neodymium pot magnets, it is critical to understand the maximum operating temperature of each grade of magnet. Neodymium pot magnets operate best at lower temperatures, they even get stronger as the temperature gets colder, to a point of approximately -130°C. However, some grades of neodymium pot magnets can also be exposed to very high temperatures before their properties begin to change and they lose their magnetism, either temporarily or permanently.

 

As a rule neodymium pot magnets lose 0.11% of their magnetism for every 1 degree celsius rise in temperature. This small loss is fully recoverable on cooling, providing that the maximum operating temperature is not exceeded. If it is exceeded, then the small loss will not be recovered on cooling and successive hot-cold cycles will see the magnetic performance deteriorate.

 

The two letters following the grade name determine the temperature rating and represent the highest operating temperature the magnet can withstand before its magnetic properties are critically affected. These ratings should always be treated as a guide value as other factors such as size and shape also have an impact on the performance of a magnet at high temperatures.

 

Regular neodymium pot magnets are strongest operating up to temperatures of 80°C but after this point, they will lose their magnetic output. On the other hand, grades with a ‘VH/AH’ rating can operate in temperatures up to 230°C.

 

Neodymium pot magnets can also be affected by permanent demagnetisation fields and radiation so it is important to always fully understand the environment that the magnet will be used in. For example, a neodymium magnet in free space will demagnetise at a lower temperature than the same sized magnet connected to a piece of mild metal.
