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.

How is neodymium used in everyday life?
Neodymium magnets, when used correctly and cautiously, have many great applications. They are used in magnetic resonance imaging (MRI) machines, resulting in ”open” MRI machines. They can be used to hold earrings on an ear without a piercing. They are used in motors, door locks, and even children’s toys!
What products are made from neodymium?
Neodymium magnets are used for:
- Dentures. Tiny neodymium magnets can be used for attachments in corrective devices or for holding together replacement dentures where several teeth are missing.
- Door catches.
- Motors and generators.
- MRI scanners.
- Magnetic therapy.
- Lifting machinery.
- Magnetic separators.
- Reed switches.
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.
How is neodymium used in phones?
Neodymium magnets are used for voice coil motors in smart phones because even a very small magnet is very powerful and can actuate the auto-focus mechanism in a fraction of a second.
Who owns the most neodymium?
Today, that supply is coming from China. More than 80 percent of the world’s neodymium is produced there. In 2017 alone, China mined 105,000 metric tons of rare earth metals, while the U.S. has only produced about 43,000 metric tons in the last 20 years combined.
Who produces neodymium?
China
Neodymium is primarily mined as part of a conglomerate with other rare earth elements in the monazite and bastnaesite mineral deposits. Historically, a single mine in California produced most of the world’s rare earth minerals, but since the early 90s, China has become the world’s primary source.
How is neodymium used in society?
Neodymium glass is used to make lasers. These are used as laser pointers, as well as in eye surgery, cosmetic surgery and for the treatment of skin cancers. Neodymium oxide and nitrate are used as catalysts in polymerisation reactions. Neodymium has no known biological role.
What are the main uses of neodymium?
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 cerium is used for?
Uses of cerium
Cerium oxide is used in incandescent gas mantles, as a glass polishing agent and as a catalyst in self-cleaning ovens. Cerium is also extensively used in the film and television industry in carbon arc lighting for studio lighting and projector lights.
How many Tesla is a neodymium magnet?
As previously mentioned, neodymium magnets can create magnetic fields with up to 1.4 teslas. In comparison, ceramic magnets generally produce magnetic fields with just 0.5 to 1 teslas. Not only are neodymium magnets stronger, magnetically, than ceramic magnets; they are harder as well.
Can neodymium magnets cause health problems?
Neodymium magnets are perfectly safe to use, as long as you handle them with proper care. Magnetic fields are not dangerous to humans at all. Though, magnets can damage some electronic devices. For example, TV’s, hearing aids, watches, credit cards, and computers can all be damaged to magnets.
Are neodymium magnets radioactive?
Five of them are stable—neodymium-142 (27.13 percent), neodymium-146 (17.19 percent), neodymium-143 (12.18 percent), neodymium-145 (8.30 percent), and neodymium-148 (5.76 percent)—and two are radioactive, neodymium-144 (23.80 percent) and neodymium-150 (5.64 percent).
Who should not wear magnetic bracelets?
Despite the popularity of magnetic bracelets, science has largely disproven the effectiveness of such magnets in treating chronic pain, inflammation, disease, and general health deficiencies. Don’t use magnets as a replacement for proper medical attention, and avoid them if you have a pacemaker or use an insulin pump.
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 improve blood circulation?
Two physicists searching for a novel way to prevent heart attacks and strokes have discovered that strong magnetic fields can dramatically reduce the thickness, or viscosity, of blood flowing through a tube.
Does Tesla use neodymium?
The U.S. electric car company Tesla will be using both kinds of motors. Even though auto sales dropped during the pandemic, demand for neodymium magnets in EVs went up 35 percent last year alone.
Does Tesla use rare earth metals?
Tesla started in 2019 to combine engine types. Its S and X models have two motors: one with rare earth magnets, one without. The induction motor provides more power, while the one with permanent magnets is more efficient, Tesla said: Including a rare earth motor boosted the models’ driving range by 10%.
Where does Tesla get neodymium?
But these rare earth magnets, mostly made of neodymium (NdFeB), are almost entirely mined and processed in China. And as tensions grow between China and the US, automakers are under increasing pressure to find more localized sources of these key materials.
Who makes tesla magnets?
As a leading magnet supplier across the world, Stanford Magnets has been involved in R&D, manufacturing, and sales of magnets since the 1990s.
