We’ve all used or at least heard of magnets before, even as adults we still stick them on our kitchen fridge maybe to spell our names or for just plain old decorations. But did you know magnets are of different types. Have you ever head of neodymium magnets. Eh! Before this article me neither. Well I had seen its applications before but never really gave much thought to the details of the magnet.
So what is Neodynium magnet?
A neodymium magnet is a type of rear-earth magnet. it is also known as NdFeB, NIB or Neo magnet because they are made from an alloy of neodymium, iron and boron. First developed in 1992 by General motors and Sumitomo special metals as a response to the high prices of Samarium-cobalt magnet neodymium magnets turn out to be the strongest type of rare-earth permanent magnet.
Neodymium magnets are very resistant to high temperature, and they can even withstand heat exceeding 200 degrees Celsius.
Did you know that the attraction between two neodymium magnets is so strong that if placed close enough together, they can collide and shatter.
Here are some of the uses of neodymium magnets.
Wind turbine generators use neodymium-iron-boron magnets to produce electricity.
High-strength neodymium magnets are often used to power their DC motors of Hybrid and electric vehicles.
When you put your mobile phone on vibrate mode, the rapid movement and subsequent sound during the vibration is caused by a miniature neodymium magnet inside the device.
Neodymium magnets are often used in State-of-the-art audio headphones and speakers, which enable improved sound quality as well as a full spectrum of bass.
Different medical equipment’s rely on neodymium magnets. For example, neodymium magnets are an essential component of an MRI scanners’ ability to give an internal view of the human body without radiation.
During the waste removal and recycling processes, the magnetic separators that are used, are usually of the neodymium variety. Plus, neodymium magnets are best for removing ferrous particles in the industrial processing chain.
It is also used in magnetically coupled pumps. It is even used in jewelries.
