Prerequisite of Neodymium Magnets

A detailed investigation about the physical and thermal attributes of the strong neodymium magnetic materials gives the following specification.

Magnetic Plating or Coating:

Neodymium magnets are the strongest magnets among all mother kinds of magnets available in the market. It is a composition of the metal Iron, Neodymium and Boron in a specific proportion. The iron element of the magnet may cause rust over the period of time if exposed to the open environment. So in order to strengthen the brittle magnet material and to protect it from corrosion, plating or coating over the magnet is a best option. A lot of coated materials are there for which are widely used for coating a magnet. However the best option among all is the nickel platting. The technique of nickel platting is a process of triple plated coating. The three layer coating comprises of separate coating of nickel, copper, and nickel again. This repeated three layer coating make the metal strong and durable enough as compared to single nickel plated magnets. Even you will find the gold plated magnets with quadruple coated with nickel, copper, and then nickel again with a final top coating of gold.

Machining:

Neodymium magnets are brittle in nature. So there is a risk of getting it break into pieces while doing machining on them. The material is however more likely to chipping and cracking, that is the reason why it is not suitable for normal machining. The machining process generate heat, which may cause the neodymium demagnetize its magnetic field. Thus machining of this magnet is not advisable.  

Demagnetization:

Rare Earth Neodymium magnets possess a great capacity of high resistance to demagnetization. Neo magnets are permanent in nature that means it almost won’t lose their magnetization even if it is dropped. However the risk of losing the strength of the magnet lies when it is heated over a maximum operating temperature of 176°F (80°C). This may be the reason of a complete demagnetization of the N grades magnet.

Strength:

If you are a novice in the field of handling a neodymium magnet, then be careful in your act. Follow all the safety cautions before dealing with the magnet. Always cover your hands and protect your eyes through gloves and goggles respectively in order to keep yourself protected from the hazards of the metal. Magnets have an amazed strength. So if it breaks down into tiny sharp particles, then the magnet particles will fly in the air and can get into your eyes. Those sharp particles are not less harmful than glass particles.
