What is a neodymium magnet used for?

In the field of information technology, neodymium magnets are particularly used in hard disc drives, mobile phones, video and audio systems of television [1]. Neodymium magnets are also commonly used in magnetic separators, filters, ionizers, in production of on–off buttons, safety sector and security systems.

What does a neodymium magnet do?

Neodymium magnets are the strongest permanent magnets commercially available, anywhere in the world. They provide unparalleled levels of magnetism and resistance to demagnetisation when compared to ferrite, alnico and even samarium-cobalt magnets.

What can you use neodymium for?

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 is neodymium used for in everyday life?

Neodymium magnets are permanent magnets made by mixing neodymium, iron, and boron to make an alloy. They are used in many applications, including motors, earrings, children’s toys, and open MRI machines. … When neodymium is mixed with praseodymium it forms didymium glass.

What are two dangers of neodymium magnets?

Neodymium magnets can jump together, pinch the skin and cause serious injuries. Neodymium magnets will leap and slam together from several inches to several feet apart. If you have a finger in the way, it can get severely pinched or even broken. Neodymium magnets are brittle – and can easily shatter and break.

Do neodymium magnets affect electronics?

The strong magnetic fields near neodymium magnets can damage magnetic media such as floppy disks, credit cards, magnetic I.D. cards, cassette tapes, video tapes or other such devices. They can also damage televisions, VCRs, computer monitors and CRT displays. Avoid placing neodymium magnets near electronic appliances.

Can neodymium magnets damage cell phones?

Will the magnet hurt my phone? We still get asked every day — “Will a magnet hurt my phone?” The simple answer is “NO.” Apple iPhone and Android devices use NAND flash memory, which is immune to magnets. … Even the strong Neodymium magnets we use for our cases are only a fraction of the size and power he uses.

What is neodymium used for in a smartphone?

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.

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.

Can wearing magnets be harmful?

Although they have been used in various diagnostic devices in the health sector and as therapeutic tools, magnets are potentially harmful to the body and pose increased risk of accident.

Is neodymium harmful to humans?

Health effects of neodymium

Neodymium is mostly dangerous in the working environment, due to the fact that damps and gasses can be inhaled with air. This can cause lung embolisms, especially during long-term exposure. Neodymium can be a threat to the liver when it accumulates in the human body.

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).

What are 3 interesting facts about neodymium?

The name combined means new twin. Neodymium is one of the more reactive lanthanide rare-earth metals and quickly oxidizes in air. The element should be kept under an oil or sealed tightly in a plastic material. The metal has a bright and silvery luster.

What does N52 mean?

N52 is shorthand for a neodymium magnet grade with an energy product or BHMax of 52MGOe (MGOe stands for Mega-Gauss Oersteds).

Are Neodymium magnets safe to wear?

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.

What shape of magnet is strongest?

The strongest part of a magnet is concentrated at the poles. That is why a horseshoe shape is considered the strongest and can be very useful to create if you want to lift heavy objects or want to make a bar magnet stronger.
