Neodymium Magnets The Wonder Magnets

What are Neodymium magnets?

Neodymium magnets are a type of rare earth magnets which are the strongest rare earth magnets and can be very risky if handled improperly.  These magnets are particularly strong for their little size and are metallic in look. Neodymium magnets are not the same as rare earth magnets.

The most widely used sort of rare-earth magnet is an enduring magnet prepared from an alloy of neodymium, iron along with boron to form the Nd2Fe14B tetragonal crystalline structure. Neodymium magnets are the resilient type of permanent magnets commercially made available and introduced in 1982 by General Motors along with the Sumitomo Special Metals.

Why are they special?

There are several attributes of Neodymium magnets that distinguish them from other magnets and are the most durable of all rare earth magnets. They are the sturdiest permanent magnets that exist nowadays and have a very high resistance to demagnetization. This makes them quite significant in several kinds of industrial uses and also commendable in high heat.

What are they used for?

Neodymium magnets are used for many purposes and in industries, commercially as well as can even come handy around the house. They are often used in machines made for the health industry, for magnetization, to make magnetic separators and magnetic filters as well as for the magnetic ionization. The security industry uses them for alarms and switches including with the security systems. They are widely used in hard drives of computers, telephonic applications, television and video applications and chip detectors. They are also very popular in the manufacturing of generators.

The world famous, NASA uses Neodymium magnets for the purpose of upholding muscle tone in astronauts in the course of space flights including with its use in MRI scanning machines. Their familiarity among students of advanced Physics for experimentation and research purposes is a common practice. They have a wide variety of uses and thanks to their low cost and application friendly attribute are graded according to their maximum energy product. 

The power and magnetic field homogeneity on neodymium magnets has also unlocked new applications in the medical field with the institution of open MRI scanners used to image the body in radiology departments as a substitute to superconducting magnets that consume a coil of superconducting wire to create the magnetic field.
