Magnet Common Sense As we all know, magnets are very useful in our daily life. To let those who are new to the world of magnets have a better understanding of them, in this article, we’ll introduce some common sense of magnets. A Brief History of Magnets The ancient Greeks and Chinese discovered a naturally [...]
Motor Magnets for Electric Fans Ferrite magnets are fabricated by calcining the mixture of Barium or Strontium carbonate and iron to form a metallic oxide. Almost all of ferrite arc magnet is used in motor applications. As the core component of the permanent magnet direct current (DC) motor, ferrite arc magnet is commonly used in [...]
Ferrite Magnets Replace Rare-earths in EV Motor Yaskawa says it has developed an electric vehicle (EV) motor that avoids the need for neodymium magnets, using much cheaper and easier-to-obtain ferrite magnets instead. The development is intended to reduce the company’s dependence on rare-earth materials, such as neodymium and dysprosium, whose prices have fluctuated widely in [...]
Magnets for Motor Applications Magnets and Assemblies from MPCO Magnetic Products can be found in many types of motors, generators, and actuators. Rare Earth magnets (Samarium Cobalt and Neodymium), or ferrite (ceramic) magnets can be used in magnetic motor and vehicle magnet applications. Rare Earth magnets are typically two to three times stronger than ferrite [...]
Alnico vs Ceramic Magnets – How Do They Affect Guitar Pickup Tone? Taking a close look at the differences between alnico and ceramic magnets and their effect on tone. When choosing a new pickup for your guitar, consider the magnet, one of the essential, yet complicating elements involved in the sound creation process. We’ll try [...]

Permanent Magnets Operating Temperatures All Permanent Magnets experience variations in field strength (flux density) as the ambient temperature increases or decreases. How these variations in operating temperature influence magnetic strength depend on the type of magnetic material and the degree above or below ambient temperature in which they are expected to operate. The shape of [...]
FERRITE MAGNETS FERRITE MAGNETS are composed of barrium/strontium carbonate and iron oxide. They are charcoal gray in color and usually appear in the forms of discs, rings, blocks, cylinders, and sometimes arcs for motors. Attributes of Ferrite Magnets - High intrinsic coercive force Tooling is expensive Least expensive material compared to alnico and rare earth [...]
Hard Magnetic Materials Magnetic materials can produce magnetic fields, which generate forces attracting or repelling ferromagnetic materials and other magnets. Magnetic material can be divided into soft and hard magnets. Soft magnets are those materials easy to magnetize and demagnetize, while hard magnets are difficult to do so and retain strong magnetism after the removal [...]
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 [...]
