Permanent Magnet Stability The ability of a permanent magnet to support an external magnetic field results from small magnetic domains “locked” in position by crystal anisotropy within the magnet material. Once established by initial magnetization, these positions are held until acted upon by forces exceeding those that lock the domains. The energy required to disturb [...]
Plastic Bonded Pressed Magnets / Plastic Bonded Magnets Plastic bonded pressed magnets are the result of the union between thermoplastic binders and permanent magnet powders, and can be made in isotropic or anisotropic qualities. Pressed magnets are magnetic products manufactured with high precision and tailored for each application. Type of material Magnetic powders: ferrite or [...]
Orientated Magnets Direction, Direction of orientation For ‘Orientated Magnets Direction / direction of orientation’ it is understood the position of the magnetic cristals in a specific direction. In the correct direction, the magnet reaches its magnetic values and thus, should be magnetized in this direction. The direction of orientation is achieved by exposing the magnetic [...]
Accelerator Magnets – Powerful and High Heat Permanent Magnets After the invention of the alternating gradient principle, researchers began to use permanent magnet in accelerators. It shows that the magnetic fields could be used to control the transverse envelope of charged-particle beams. Since that time, permanent-magnet materials have found wide application in the modern charged [...]
Accelerator Rare Earth Magnet For CERN Accelerator Rare Earth Magnet For CERN of MPCO has been committing to working with various research institutions around the world. We supply them high-quality rare-earth magnets. CERN is one of them. They use neodymium and samarium cobalt magnets on accelerators. Accelerator Rare Earth Magnet For CERN What [...]
Magnetic Encoder Engine Technology An optical encoder uses light (optics) to identify unique positions for the encoder. A magnetic encoder uses the same principle to determine a position as an optical encoder, but it does it using magnetic fields rather than light. With a magnetic encoder, a large magnetized wheel spins over a plate of [...]
Permanent Magnet Materials Permanent magnet lodestones contain magnetite, a hard, crystalline iron ferrite mineral that derives its magnetism from the effect the earth's magnetic field has on it. Various steel alloys can also be magnetized. The first big step in developing more effective permanent magnet materials came in the 1930s with the development of Alnico [...]
Magnet Background A magnet is a material that can exert a noticeable force on other materials without actually contacting them. This force is known as a magnetic force and may either attract or repel. While all known materials exert some sort of magnetic force, it is so small in most materials that it is not [...]
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 [...]
Parylene Coated Magnets What is Parylene coating? Parylene is the common name of Poly-para-xylylene, and it was prepared by the researcher in University of Manchester in 1947. The parylene first applied to U.S military and aerospace industry after Union Carbide prepared parylene thin film by the deposition process. Nowadays, parylene coating are widely used in [...]
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 [...]
