What is a neodymium magnet?

Neodymium, bromine and iron – these three components were enough to get a kind of magnet that produces a very strong magnetic field. This, in turn, makes it extremely attractive. Among other things, thanks to this property, it has found such wide application in many devices. What is a neodymium magnet characterized by? Where it can be used?

Neodymium magnet - what is it?

Neodymium magnets are permanent magnets. This means that they do not lose their properties over time. They were invented relatively recently, in the early eighties of the last century. Although the composition of this magnet is based on neodymium, this element is combined with bromine and iron to form the compound Nd2Fe14B.

It is produced using the powder metallurgy method. It consists in pressing powdered ingredients at high temperature and in a strong magnetic field. The production process ends with covering the magnet with a nickel, zinc or phosphate coating.

What are the characteristics of neodymium magnets? First of all, they generate the strongest magnetic field of all magnets known today. They are resistant to high temperature.

What are the applications of neodymium magnets?

Even a small neodymium magnet is able to generate a strong magnetic field. It is this feature that makes them extremely popular – they can be used even in small devices.

They can be found in various types of counters, compasses, and even in specialized medical equipment. They are invaluable in the production of accessories and electronic devices. They are used in televisions, speakers, computer monitors, as well as in microphones and CD players. They can be found in many children’s toys.

Neodymium magnets are also used to produce water magnetizers, i.e. installations aimed at water treatment and preventing scale build-up in pipes. They are also used on a large scale in industry and specialized machines. Their task is to improve elements such as generators and motors.
