Neodymium is used with iron and boron to create powerful permanent magnets, also called NIB magnets. NIB magnets are used in computers, cell phones, medical equipment, toys, motors, wind turbines and audio systems. Neodymium is used as a crystal (neodymium-doped yttrium aluminum garnet) in lasers.
What is the main use of neodymium?
The most important use for neodymium is in an alloy with iron and boron to make very strong permanent magnets. This discovery, in 1983, made it possible to miniaturise many electronic devices, including mobile phones, microphones, loudspeakers and electronic musical instruments.

Is neodymium harmful to humans?
Neodymium magnets are perfectly safe for humans and animals as long as you handle them with care. … Some neodymium magnets are strong enough to cause some serious damage to your fingers and/or hands if they get jammed between a strong magnet and metal or another magnet.
What do Neodymium magnets stick to?
But exactly what types of metals do they attract? Neodymium magnets are known as the strongest magnet material available and have the highest holding strength to these metals. They are called ferromagnetic metals containing mainly iron, nickel and rare earth alloys.
Are Neodymium magnets illegal?
As of January 2017, many brands of magnet spheres including Zen Magnets have resumed the sale of small neodymium magnet spheres following a successful appeal by Zen Magnets in the Tenth Circuit US Court of Appeals which vacated the 2012 CPSC regulation banning these products and thereby rendered the sale of small …
Why neodymium is most paramagnetic?
Neodymium magnets have higher remanence, much higher coercivity and energy product, but often lower Curie temperature than other types. Neodymium is alloyed with terbium and dysprosium in order to preserve its magnetic properties at high temperatures.
Does neodymium conduct electricity?
Does neodymium conduct electricity? … Neodymium magnets (and the nickel plating commonly used on their surface) do conduct electricity. Not as well as, say, copper or aluminum, but it’s a conductor.
Are Neodymium magnets conductive?
The outside of new neodymium magnets are coated with Nickel, which is a good conductor. The magnets themselves are mostly Iron. Also, if you happen to have a multimeter, which you should if making electrical circuits, just test with the resistance settings.
Does the human body use neodymium?
The amount of neodymium in humans is quite small and, although the metal has no biological role, it can be effects on parts of the body: neodymium dust and salts are very irritating to the eyes. Ingested neodymium salts are regarded as only slightly toxic if they are soluble and non toxic if they are insoluble.
Can magnets damage the brain?
Prolonged exposure to low-level magnetic fields, similar to those emitted by such common household devices as blow dryers, electric blankets and razors, can damage brain cell DNA, according to researchers in the University of Washington’s Department of Bioengineering.
Do magnets affect human body?
Magnetism is not felt by the human senses in any obvious way, nor is there any substantial evidence that it is harmful. Yet it does have subtle effects on vision and heart performance.
Are 2 magnets stronger than 1?
Two magnets together will be slightly less than twice as strong as one magnet. When magnets are stuck entirely together (the south pole of one magnet is connected to the north pole of the other magnet) you can add the magnetic fields together.
Why are neodymium magnets dangerous?
Neodymium magnets create strong magnetic fields around them, which can interfere with pacemakers, ICDs and other implanted medical devices. This is because many of these devices are made with a feature that deactivates the device in a magnetic field. Keep neodymium magnets away from magnetic media.
How long do neodymium magnets last?
