What Is It All About Magnetic Electricity?

What Is It All About Magnetic Electricity? Along with the development of technology, people get the opportunity to experience new types of magnetic materials. The scientists are working hard to develop highly sensitive magnetic materials that can be used to provide effective appliances in the present world. For example, these highly sensitive magnets can be [...]

AlNiCo VS Ceramic Pickups

AlNiCo VS Ceramic Pickups If you're into guitar or bass guitar pickups and mods, you probably hear the words "AlNiCo" and "Ceramic" a lot. These terms refer to the magnetic bar located inside the actual guitar pickup of your guitar. Most guitar manufacturers mention the pickup types they use on each guitar model but some [...]

MULTI-POLE MAGNETIC CIRCUIT COMPARISONS

MULTI-POLE MAGNETIC CIRCUIT COMPARISONS Permanent magnets can be magnetized with two or more (4, 6, 8, etc.) poles, using permanent or pulse magnetic flux. Pulse magnetization allows achievement of larger magnetic fields necessary for Nd-Fe-B or Sm-Co magnets. Multi-pole magnetization requires special magnetization heads with preformed windings which allow achievement of required distribution of magnetic [...]

Magnet Quenched Powder

Magnet Quenched Powder HSMAG magnetic powders are based upon Nd-Fe-B alloy compositions that are quickly solidified from their molten state at high cooling rates. This rapid solidification results in a material that has a precise grain structure. Due to the small grain size, these materials are magnetically isotropic. Unlike the very fine, anisotropic powders that [...]

The Present Situation And Prospect Of AlNiCo Industry

The Present Situation And Prospect Of AlNiCo Industry As is known to all, since the AlNiCo magnets came out in the 1930 s, was widely used in many areas. Especially in the '60 s to reach peak, the world has an annual capacity of 40000 tons of AlNiCo magnet, but by the 70 s began [...]

Plastic Bonded Magnets

Plastic Bonded Magnets Plastic bonded magnets are particle composites with permanent-magnet powder embedded in a plastic binder. Hard ferrite (HF), various SmCo and NdFeB powders and, to a very little extent, AINiCo alloys are used as magnetic powder. For embedding the magnetic particles, thermoplastic binders as, for instance, polyamide (PA) or polyphenyl sulfide (PPS) and [...]

Circumferentially Oriented Magnets

Circumferentially Oriented Magnets Circumferentially orientation and magnetizing pattern is not available for arc and ring magnets which comprised of Neodymium magnets and Samarium Cobalt magnets. The most common circumferentially oriented magnets are common Alnico horseshoe magnet, however, whether or not Alnico ring magnets can be oriented and magnetized through circumferential direction? In fact, Alnico ring [...]

Understanding Magnetic Permeability

Understanding Magnetic Permeability Magnetic Permeability is a value that expresses how a magnetic material responds to an applied magnetic field. If a material's internal dipoles become easily oriented to an applied magnetic field, that material is regarded as being a high-permeability material. If the material's internal dipoles do not become easily oriented to an applied [...]
