Magnetic Measurements Magnetic Measurements For measuring of the fundamental magnetic properties of a material (Br, bHc, iHc, BHmax, demagnetisation curve), Hysteresisgraph or BH-tracker is used. A BH-tracker consists of an iron (usually FeCo) yoke to form a closed circuit, electromagnets to create the demagnetizing field and fluxmeters to determine the demagnetizing field and the materials [...]
How Much Temperatures Can be Rare Earth Magnet Heat? Neodymium Magnet Damage From High Temperatures If a Neodymium Rare Earth Tube Magnet is put into a red-hot fire, then it would not be surprising if the magnetic properties are destroyed. However, what if the same Tube Magnet is just exposed to steam being flushed through [...]
Magnetic Simulation Magnetic simulation is the perfect design tool while approaching a complicated magnetic problem. With our know how, it can be used to achieve high level magnetic design. We can simulate and calculate special magnetic arrays, magnetic force (for example if you need a very unified magnetic field), torque and many more parameters. [...]
GBD SINTERED NFFEB MAGNETS – GRAIN BOUNDARY DIFFUSION Technology GBD sintered ndfeb magnets are an environmentally friendly solution. One of the main topics in global permanent magnet research is the reduction of HRE, without degrading the performance of NdFeB permanent magnets, but rather improving them. A promising approach to achieve this goal is the grain [...]
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 [...]
