Neodymium is rare earth element, which is employed to produce powerful magnets. The magnetism scale of Neodymium or NIB magnets can range from N24 – N55, which can escalate to N64. Its magnetism scale depends on the composition, shape, and production method.
Manufacturers gather rare earth elements and sieve them to separate usable Neodymium from other minerals. Neodymium is grinded into small powder that can be resealed in a desired shape along with boron and iron. Chemical formula of neo is Nd₂Fe₁₄B.
The iron property of mechanical fragility also gets included, which can pose issues, when magnetic power escalates beyond endurance limits. For example, if the neodymium magnet is connected with a part that includes lot of rapid momentum, it can cause cracking or chipping.
Neodymium is susceptible to temperature differences. They can demagnetize or crack at temperatures above 176°F. Therefore, neodymium magnets are not used in applications that will get exposed to high temperatures.
Neodymium magnets possess high magnetic energy than the other form of magnets. Moreover, they are less expensive in comparison.
Application of Neodymium magnets
Us neodymium magnets are used in industrial and commercial sector. Let’s look at the kinds of application that uses Neo.
Locating nails under hardwood, tile or linoleum flooring
Re-magnetize old magnets
Attaching small GPS units to vehicles, which can be removed easily
Banners, signs and floats can be held successfully on cars
Trailer hitch rods for easy position of trailer hitch to tow ball
Dents can be removed from musical instruments made from brass
Hanging signs from the warehouse steel ceilings or beams and also excellent options for holding labels and signs to steel shelving
For holding a pacifier within doll’s mouth
Large Neodymium magnet help to erase audio and video tapes, if you don’t have electromagnetic degausser
Magnets can be used to hold several tools and keep your garage organized
Smart metal detectors help to locate metals quickly
Carpenters make use of invisible magnets to create magnetic cabinet latches
Magnets can hold the wings of model aircrafts, which can be released in a crash, thus reducing splintering and maintenance time
Slot cars make use of traction magnets, which helps the car to stick to the track, during faster lap times
Christmas decorations can be hung easily on steel front doors. Christmas lights can be hung on aluminum rain gutters
In generators the stronger the magnet the more efficiently it works
Strong magnets help to locate meteorites that fall nearby
This list of magnet application is endless. However, magnetic neodymium users must handle it with caution. Magnets in kid’s toys need to be monitored because they can swallow it, which can be infectious. Large NIB magnets with high magnetism field can spread in the room and metals present can get attracted towards the magnet just like a flying object. If it is connected to something with rapid momentum the magnet can get shattered and hurt you. Therefore, it is vital to know the kind of magnet present in the equipment you handle.
