History of Permanent Magnets Lodestones The history of permanent magnets goes back to ancient times. Records from early Greek, Roman and Chinese civilisations make reference to rare and mysterious stones called lodestones. These lodestones could attract each other and also small pieces of iron. When suspended from a thread it was noted that they always [...]
The Manufacturing Process of Sintered Neodymium Magnet - How Neodym Magnets are made? Sintered neodymium magnet is manufactured by vacuum powder metallurgy process. The manufacturing process is as follows: 1. Raw Material Neodymium (Nd), Iron (Fe), Boron (B) and other addictives are measured according to the preferred element composition. Raw NdFeB material Raw Material of [...]
Grain Boundary Diffusion- Conserving HREE in NdFeB Magnets Grain Boundary Diffusion is an important new advance in Neodymium magnet production technology. Heavy Rare Earth Elements (HREE) are delivered directly to critical areas of the magnet’s microstructure. These areas are where HREE are the most effective at increasing the properties of the magnet to withstand high [...]
How Neodymium Magnets are Made The method for manufacturing Neodymium Iron Boron magnets is as follows: MELTING OF THE ALLOY UNDER VACUUM The Neodymium metal element is initially separated from refined Rare Earth oxides in an electrolytic furnace. The Neodymium, Iron and Boron and the other chemical elements are weighted and put in a vacuum [...]
Rare Earth Properties - Lanthanides and Actinides When you look at the Periodic Table, there is a two-row block of elements located below the main body of the chart. These elements, plus lanthanum (element 57) and actinium (element 89), are known collectively as the rare earth elements or rare earth metals. Actually, they aren't particularly [...]
Investigation of magnet segmentation techniques for eddy current losses reduction in permanent magnets electrical machines Reducing eddy current losses in magnets of electrical machines can be obtained by means of several techniques. The magnet segmentation is the most popular one. It imposes the least restrictions on machine performances. This paper investigates the effectiveness of the [...]
How Magnet Therapy Work - Bio Magnet Magnets therapy in China – Last one year we are researching how to control Pain through natural therapy. Finally we found Magnet Therapy for Pain Relief. There are several ways to block the transmission of the pain impulse to the brain. One is the use of an anesthetic [...]

Strong Force Cell Phone Magnet, smart phone mobile telephone micro magnets for APPLE, HUAWEI, XIAOMI, HTC, SAMSUNG, LG, OPPO... Sophisticated smart phone applications such as maps or augmented reality use measurements of the Earth's magnetic and gravity fields to work out the orientation of the phone.A typical smart phone has three magnetic field sensors, fixed [...]
Electromagnets & Solenoids Electromagnets are a non-permanent magnets that produced magnetic field. The magnetic field is created by a flow of an electric current through the coil. The magnetic field disappears when the current ceases (or in the case electromagnets of a permanent electromagnet, the magnetic field is present until a current is applied). As [...]

Strong Magnet Magnetization Orientation How do you differ from the north pole of a strong magnet without being marked? Obviously, it is impossible to distinguish between eyes alone. The compass can be used to approximate the powerful magnet, and the pointer to the north pole of the earth points to the south pole of the [...]
