You may not have heard of neodymium magnets (also known as NdFeB or Neo magnets) if you are not in the world of magnets, however, you would be surprised when you know what they are used for in everyday life. They are the strongest known type of permanent magnet available and are used for many things both industrial and commercial. Without this type of rare earth magnet, many technological advances that we probably take for granted would not have been possible!
What are Neodymium Magnets made from?
Neodymium magnets composition is made up of a lot of neodymium, iron and boron. The combination and amount of each can vary depending on the strength required.
As neo magnets are so strong, they have replaced many other magnets such as ceramic magnets in many uses.
What are Neo Magnets used for?
MRI imaging – medical imaging devices that are widely used today in the medical field use neo magnets. The magnets affect the electrons in your body, then capturing an image of the effect.
Microphones headphones and loudspeakers – current-carrying coils are used with permanent magnets which convert electricity into mechanical energy. This then changes the pressure of the surrounding air to create sound.
Dentures – To keep dentures securely in place tiny neodymium magnets are used.
Door catches – Commercial and residential buildings often use doors with neodymium magnetic catches.
Bracelet and Necklace Clasps – Neo magnets keep clasps strongly together
ABS Anti-lock brake sensors – anti-lock brakes in cars use neodymium magnets wrapped inside copper coils.
Magnetic separators and metal detectors – Both of these techniques are used widely in industries such as recycling, quarrying and welding
