Neo magnets are one of the strongest rare earth magnets. They are very popular too because they come for a fraction of the price of other rare earth magnets which are much less powerful. They have a tetragonal crystalline composition which makes them a permanent and highly durable metal. It consists of Iron, Neodymium and boron.
These rare earth magnets were invented in the year 1982 by General Motors and Sumitomo Special Metals, and today they are one of the strongest and affordable types of rare earth magnets. These magnets have gained so much of popularity in the recent years due to its compact structure and the properties which makes it strong, durable and cost effective too.
Due to these properties, it has replaced other types of magnets from the common household items such as motors, hard disk drives, magnetic fasteners etc.
Properties of Neo magnets
Neo magnets have become so popular due to its properties and also due to their very affordable costs. One of the most important properties of these magnets is its Coercivity. The high magneto crystalline structure makes it so much coercive.
They also have a very high resistance against demagnification. This is the reason because of which these magnets are widely used in industries nowadays. Apart from Coercivity, Remanence is also very crucial property of Neo magnets. Due to this property, the metal has excellent field strength and is able to attract iron or another magnetic piece strongly from quite a distance.
Like every other magnet, Neo magnets also have a curie temperature in which it loses its magnetic properties. Care should be taken while handling this magnet in high temperature fields as they could catch fire. These magnets are excellent in strength too.
In terms of strength, these magnets are one of the best magnets found in the market. All these properties make this magnet suitable for use in different appliances replacing any other type of magnets.
Applications of Neo magnets
Due to the yet unbeatable properties of these magnets, they have replaced alnico and ferrite magnets. They have also replaced other magnets from different instruments such as computer hard drives, guitars, audio speakers, motors, CDs, DVDs, mobile phones, digital cameras, watches etc.
These magnets come in different sizes and shapes. The flexibility in size and shape makes it perfect for use in different appliances according to the requirement. These magnets have become so popular that major car manufacturing companies are also trying to implement these magnets instead of using other magnets.
In short, Neo magnets are becoming very popular and it’s not too far when Neo magnets would replace all other types of magnets.
