AlNiCo Magnets and Music Revolution

AlNiCo Magnets and Music Revolution

AlNiCo pickup magnets played a huge part in the development of modern electric guitar sounds.  Guitar manufacturers and musicians discovered that even on the same guitar, switching out different AlNiCo alloys resulted in drastically different musical tones.  Indeed, the use of certain AlNiCo pickups is responsible for the signature sounds associated with 50s and 60s…

The History of Neodymium Magnets

History of Neodymium Magnets banner

The origin of the neodymium magnets dates back to 1885 when Carl Auer von Welsbach, an Austrian scientist and inventor, separated didymium into the new separate elements neodidymium (“new didymium”) and praseodidymium (“green didymium”).  In time, the element names would change to neodymium and praseodymium. Neodymium (Nd) is the fourth member of the lanthanide ‘rare-earth…

Magnets and the Curie Temperature

Curie Temperature

The term “Curie temperature (Tc)” or “Curie point” gets frequently mentioned when discussing magnets and magnetic properties.  The Curie temperature relates to the maximum temperature a material can reach before losing its magnetic properties.  On reaching a magnetic material’s Curie temperature, the spontaneous magnetisation in the material drops to zero.  At this point, the material…

Explaining Neodymium Magnet Strength

Neodymium Magnet Strength

Neodymium Rare Earth Magnets are the strongest commercially available permanent magnets in the world.  Originally invented by General Motors and Sumitomo Special Metals in the early 1980s, Neodymium Magnets are a key component in mobile phones, computers, wind turbines, and modern cars.  The list of applications is nearly endless. As the name suggests, the prime…

An Introduction to the Halbach Array

Bunting Magnetic Assembly

Halbach Arrays feature in many common-day devices such as brushless DC motors and even the Inductrack Maglev train. The Halbach Array is a specific arrangement of permanent magnets that cancels the magnetic field to nearly zero on one side, but significantly increases the strength of the magnetic field on the opposite side. This magnetic phenomenon…
