Feature: Neodymium magnets are a type of rare earth magnet. They are very strong relative to their size. They are often referred to as rare earth magnets because they belong to the rare earth elements on the periodic table. But they are not the same as rare earth magnets. There are different types of rare earth magnets and Neodymium magnets are just one type. Neodymium magnets are the strongest permanent magnets available today.

Neo tends to be vulnerable to corrosion similar to rusting, causing the magnet to weaken and eventually break down into a powder. This problem is solved by applying a protective coating. Nickel plating or nickel/copper/nickel plating is used as a standard method, although many other protective coatings are also in use.
It is not recommended to use the magnet without a protective layer. The application of the magnet will affect the choice of coating. For example gold plating is ideal for many medical applications, rubber coating provides additional friction, rubber coated zinc plating is used in marine environments, etc.

Neodymium magnets have replaced Alnico and ferrite magnets in many applications where strong permanent magnets are required. The greater strength allows the use of smaller, lighter magnets in many applications.
