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

The origin of the neodymium magnet 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 in Santa’s Workshop

Magnets in santas workshop

Santa Claus has never been busier. Material shortages, transportation issues and the dreaded Coronavirus pandemic have stretched his elf workforce to the limits. His workshop is a hive of activity and, in amongst the organised chaos, magnets play an important role. So where are they? High Tech Toys use Neodymium Rare Earth Magnets Santa Claus…

Magnetising Fixture Winding for Magnet Ring Sensor Project

Magnetising fixture inding

Bunting’s engineering team work with companies on many magnet product designs, from concept through to manufacture.  This project focused on the feasibility of designing, manufacturing, and supplying a permanent magnet ring to produce a sinusoidally varying flux density waveform for a sensor application.  A sine wave or sinusoid is a mathematical curve that describes a…

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…

New Magnet Setter Demonstration Unit

Magnet Setters

In response to an increase in magnet design projects, Bunting-Berkhamsted has added a new Magnet Setter demonstration unit to their testing house. The BMCS-1510 Magnet Setter magnetises and sets Samarium Cobalt (SmCo) and AlNiCo magnets when connected to a compatible magnetising fixture.  The magnet setter features a built in gaussmeter for measuring the magnetic field…

AlNiCo Magnet Setter Development

Bunting Magnetics Magnetisers

Bunting engineers have developed a new Magnet Setter for AlNiCo magnets. AlNiCo Magnet Properties AlNiCo’s relatively low coercive force (Hc) means that the magnet material is easily magnetised to saturation, as well as fully or partially demagnetized by external fields. This makes an AlNiCo magnet easy to magnetise when part of an assembly, but could…
