Rare earth Neodymium magnets (NdFeB) have been available for industrial application since 1984. Neo magnets have extremely high magnetic energy and therefore are used in applications which require high powered magnets, as well as applications where size and weight reduction are of interest or need to be considered. These qualities have made NdFeb magnets preferable over the commonly used larger and less powerful Ferrite magnets.
The main raw materials NdFeB permanent magnets are rare earth metal-Neodymium (Nd) 32%,metal element Iron (Fe) 64% and nonmetal element Boron(B) 1% , and some small amount added Dysprosium (Dy), Terbium(Tb), Cobalt (Co), Niobium(Nb),Gallium (Ga),Aluminum (Al),Copper (Cu) and other elements. Ternary system neodymium permanent materials are of Nd2Fe14B compound as a matrix, its compositions should be similar with the molecular formula of compound Nd2Fe14B, but, when it is proportioning according to the composition of Nd2Fe14B compound, the magnet performances are very low, and even without magnetic, just on the actual magnets, when the content of neodymium and boron are more than on Nd2Fe14B compound, we can get the better permanent magnet performances.
Neodymium magnets can be divided into three main groups:
1.Regular Neodymium
2.High corrosion resistant Neodymium
3.Bonded Neodymium (Isotropic): Manufactured by the injection of plastic material and Neodymium into a mold. This production method yields a very precise magnet which does not require further grinding and does not suffer substantial current loss.
Neo magnets are known for their high temperature resistance, making them durable and functional in temperatures exceeding 200°C. This quality makes them ideal for heavy industry applications. Sintered Neodymium, however, is sensitive to oxidization and can develop corrosion, so magnets are usually coated with Nickel+Copper+Nickel,Nickel+Sn, Zn(galvanization), Epoxy and Passivation for their protection.

- Q:are there any materials that alternate between ferromagnetism and diamagnetism?
- If you start removing exhaust parts without tuning your engine to the new exhaust set up you are not likely to gain anything and might even loose power.
- Q:I am unsure as to whether or not the metal that moves within said field must be ferromagnetic.
- It needn't be ferromagnetic. The changing magnetic field will produce an electrical current in the copper. Feromagnetism is the metal being brought near the magnetic field taking on a strong magnetic field.
- Q:What are the characteristics of the permeability of non ferromagnetic materials and ferromagnetic materials?
- Non ferromagnetic material, if it is paramagnetic and diamagnetic material, one is greater than 1, one less than 1, but are similar to 1, ferromagnetic B-H nonlinear changes, permeability can be very large, the impact factor is also more.
- Q:The bar magnet is dropped into a bag of coins. Some coins are attracted to the magnet but some are not. Why?
- most coins are made of non-magnetic materials like copper, zinc, silver, gold. Only magnetic metals are iron, nickel and cobalt. .
- Q:do you know how to build a magnetic shield (or case) to protect the tape stripe cards using by ATM machines? I need it to be like a case which fits in a pocket and also can be made at home.thankyou.
- That's not so easy as you might think,. Magnetic fields are very hard to block, and go through most materials like their not even there. What electronics uses for shielding is iron bases metal- that is - Steel the concentrate the magnetic field within itself, protecting what ever is on the other side. General solution? common sheet metal bent to a card holder and line with some cloth.
- Q:I have a very strong magnet that I use to locate wall studs. It is flat and round with a hole in the middle. I can locate the nails the sheetrock with it. I have used it for some time now and it seems that it is as powerful as when I first got it. It got me to wondering if magnests lose any power over time or from attaching it to metal objects? Let me know what you think. Thank you
- Definitely should take her to the vet
- Q:What are the stages of the development of rare earth permanent magnet materials?
- The development of permanent magnet motor is closely related to the development of permanent magnetic material. China is the world's first found that the magnetic properties of permanent magnet materials and apply it to the practice of the country, two thousand years ago, China's use of the magnetic properties of permanent magnet materials made of the compass, played a huge role in navigation, military and other fields, has become one of the four great inventions of ancient china.
- Q:What's the difference between a permanent ferrite magnet and a NdFeB magnet?
- The difference between NdFeB magnet and ferrite magnet is mainly as follows: 1. ferrite magnet is inferior to ndfeb. 2. on the price, ferrite is much cheaper than NdFeB magnets. 3. NdFeB magnets have good temperature resistance, while ordinary NdFeB usually only 80 degrees, more than the work temperature will appear demagnetization. 4. ferrite stability is very good, it is itself oxide, very stable, NdFeB is alloy, and its easy to oxidize, must do coating protection.
- Q:I need a simple yet sophisticated meaning of a magnetic field for Homework /:
- Iron (Fe) is a transition metal in group 8, period 4.
- Q:I know that gravity accelerates objects at about 9 feet per second per second on earth, but I am curious how much if at all does a magnet accelerate an object. -How much does the mass of the magnet influence the acceleration? -If the magnet was the size of the earth, what would be the acceleration? -If their was a magnet the size of earth, would it be more dense in the center (assuming that there was no gravity, but only magnetic force)? -If it was more dense in the center, would objects be pulled more towards the center?Sorry for all the questions in one, but I am really curious.
- Clean your seat with some cleaner to remove whatever was put on there.Never use anything like armour all that will make your seat slippery.You shouldn't be sliding forward that easily.
