We all use a neodymium magnet in one form or the other; we just don't know that we do. There are so many uses and advantages of this amazing piece of human invention of which we are unaware of. One can easily find a neodymium magnet in a hard disk of a computer, headphones, and loud speakers to name a few. And these magnets are immensely powerful and enable us to do things where normal iron or ferrite magnets prove ineffective.

| Neodymium Magnets and Its Power in Electronic Circuits |
Neodymium Magnets - An Excellent Rare Earth MagnetNeodymium Magnets is no doubt the strongest and the most popular rare earth magnets. It comprises of Iron (Fe), Neodymium (Nd), and boron (B) to structure the Nd2Fe14B tetragonal crystalline composition. It is also called NIB, NdFeB, or Neo magnet. It is a permanent as well as a highly durable metal.
These metals were invented in the year 1980. Today, they are the strongest and most affordable type of rare-earth magnet. In this article I would basically like to stress up on some of the key properties of neodymium magnets. Let us start with the first one.
1. Coercivity
The high uniaxial magnetocrystalline anisotropy of this metal gives it the power to have high coercivity. They have a very high resistance to demagnetization due to their tetragonal Nd2Fe14B crystal structure. Due to this feature this metal is highly used in many different kinds of industrial applications.
2. Remanence
This metal has excellent magnetic field strength. One problem with this magnet is that it may even break off and split if it is allowed to snap together.
3. Curie temperature
It is the maximum temperature at which this metal loses its magnetism. These metals usually have a low working temperature for heat applications and can catch fire at high temperatures.
4. Strength
These items are much more powerful then any other horseshoe magnet that are available in the market. They have highest magnetic strength.
Neodymium Magnets are small yet powerful metals. These permanent metals have now replaced alnico and ferrite magnets. Now a day's these magnets are used in numerous myriad application such as computer hard disks, magnetic resonance imaging, magnetic guitars, audio speakers, motors, actuators, electronic devices, CD, DVD, mobile phones, digital cameras, watches, timer switches, cars, bicycles, fishing reel brakes, children magnetic toys, etc.
You can easily transfer these elements from one place to another. Even a small size magnet has high energy. Let me tell you that the north pole of the Neodymium metal will only attract the north pole of the other neodymium element and it will always repel the South Pole.
These elements usually come in different shapes and sizes. Now a day's market is flooded with variety of Neo magnet. You can easily find disk shaped, cylinder shaped or ring shaped objects. Let me tell you one more thing that if you will use this magnet gently then it will serve you for a lifetime. I hope now you have a good idea of this object.
Neodymium Magnets And Their Uses
These magnets are actually the strongest permanent magnet types available commercially and they have even replaced other magnet types in different application in making modern products that need the strength. Today you will find the magnets in cordless tools as motors, fasteners and even in hard disk drives. Below are some of the common uses of neodymium magnets.
Medical industry uses - The neodymium magnets are used extensively for magno-therapy by medical practitioners and physiotherapists to reduce pain. They are also sold as medical devices to wear as shoe insertions, blankets and bracelets. They stabilize iron content and hemoglobin content in blood. They are also used in dentures as to hold them together and in other corrective devices.
Iron industry uses - These magnets are used in iron industries, especially in lifting huge iron materials from iron dust whereas the weaker magnets attract dust particles. In heavy manufacturing and engineering industries the magnets lift large ferrous items and are also used as magnetic separators.
Home uses - At home the neodymium magnets are used in various ways, such as in creating door and drawer closures, fixing furniture and hanging pictures. They also prove helpful in cleaning processes around the home such as when cleaning washing machines and refrigerators or even fish tanks.
Ornamental uses - The magnets have become very common in jewelry. They attach to the skin and hold jewelry pieces without the need to pierce the skin.
Motor industry uses - This is an industry that seems to benefit most from the neodymium magnets. They are used in magnetically coupled pumps, electric motors and generators and in bearings to provide relative motion with low friction without mechanical wear even at very high speeds. Anti-lock braking system sensors also use these magnets.
Entertainment industry uses - When it comes to the entertainment industry, the permanent magnets are used in audio equipment like speakers, microphones, headphones and acoustic pick-ups.
Other uses of the magnets include use as door catches in residential, commercial and public buildings, in hard disk drives to record data, in MRI scanners, levitation devices, reed switches and print finishing. These are the magnets that are also used in galleries and exhibitions to hang artwork and in shops and restaurants to hold together point of sale displays.
The neodymium magnets are preferred over artificial ones because:
- They do not have a tendency of losing magnetic properties and they are also corrosion and erosion free
- They naturally occur in the earth's crust are therefore safe for use; there are no known serious health hazards on children and adults
- They may be a little expensive, but their benefits are enjoyable over a long period of time making the prices worthwhile

How Are Neodymium Magnets Produced?
The classical process for neodymium magnet production is done through powder metallurgy or sintered magnet process. This process requires that the neodymium, iron, and boron are melted down and cast into ingots. Once these ingots are cooled they are turned into a fine power of particles. The particles undergo liquid-phase sintering which causes the particles to magnetically align. Once the particles are aligned they are simultaneously heated and compressed to produce a magnet.
Rapid solidification is accomplished by taking an Nd-Fe-B alloy and melt spinning a thin ribbon of it. The ribbon that is produced through the melt spinning process has randomly oriented grains. The ribbon is then pulverized into small particles. A polymer is then added to the particles and that mixture is either injected molded or compressed into bonded magnets.
Several tens of thousands of tons of neodymium magnets are produced annually. These magnets are used in MRI machines, hard drives, loudspeakers, electric motors, and other applications. For example, the Toyota Prius uses 1 kilogram of neodymium to produce the motor that is in the car. Special care needs to be taken when handling neodymium magnets because of their magnetic power. Even a magnet as small as a couple centimeters have the ability to cause bodily harm if skin or other body parts get trapped between magnets. If magnets are near each other they may collide with enough force to cause them to chip. The magnetic fields are also hazardous to watches, credit card strips, magnetic media and other devices.
Of the total world production, sintered neodymium magnets make up 45,000 to 50,000 tons. China accounts for 75-80% of the world production. China is also the country where the majority of the products that are produced using these magnets are manufactured. Japan accounts for 17-25% of the production. Europe produces 3-5% of the world production annually.
The other 5,500 tons of neodymium magnets produced are the bonded type. The bonded magnets have several advantageous over the sintered magnets. They offer less flux which makes them better suited for scientific application. It is possible for them to be formed into parts that are not able to be done through the classical process. There is not eddy current loss with this type of magnet.
The use of these magnets in hybrid and electric cars, and their importance in many electronics means that production will increase in the future. This will include both the classical and rapid solidification process.

✔ Nikola Tesla’s method of magnifying electric power by neutralizing the magnetic counter-forces in an electric generator
✔ Currents are 180 out of phase with each other, Lenz's law naturally is broken
✔ Principle of Resonance to achieve Overunity
✔ Generate generators without rotating motion, but based on the principle of rotating magnets. Because magnetism varies based on electronic circuit design: coils, capacitors, Negative resistance, etc.The change of magnetism does not require the rotation of the magnet.
