The History of Neodymium Magnets
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…
Read MoreMagnets in Santa’s 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…
Read More33rd Ewing Event: Magnetics in Carbon 2050
Matthew Swallow, Bunting’s Technical Products Manager and Vice Chair of the UK Magnetics Society, reports on the society’s 33rd Ewing Conference held in Warwick, UK in December 2021 and sponsored by Bunting. This year’s annual event focused on the key role played by magnetics in tackling climate change. The seminar looked at magnet production and…
Read MoreMagnetising Fixture Winding for Magnet Ring Sensor Project
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…
Read MoreBunting Magnet Test and Development Centre Investment
Bunting has invested in expanding their Test and Development Centre at Berkhamsted in the UK where they specialise in the design, test and build of a wide range of magnet and magnetic technologies. Bunting’s Berkhamsted operation is responsible for the design and manufacture of magnets, magnet assemblies, and magnetising equipment. The range of applications for…
Read MoreExhibition Success for Bunting-Berkhamsted
Exhibiting at two shows, in different parts of Europe, over the same two days, was challenging for the Bunting-Berkhamsted team, but proved exceptionally successful. Whilst Matthew Swallow managed the stand at the Cenex LCV event at UTAC Millbrook in the UK, Stefano Maiaroli and Dr Chris Riley were in Pordenone in Italy at the Coiltech…
Read MoreMagnetising and Magnet Technology at Coiltech Italia 2021
With a growth in sales of magnetising equipment and magnet assemblies into Italy in 2021, Bunting-Berkhamsted is exhibiting at the 12th Coiltech Italian 2021 international trade fair (stand 8-D27). Coiltech also hosts the World Magnetic Conference. The exhibition focuses on materials and machinery for the production and maintenance of electric motors, generators, power and distribution…
Read MoreMagnets and the 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…
Read MoreMagnetics Importance for Electric Vehicles at Cenex-LCV
Magnets and magnet assemblies, both essential for transport electrification, are the focus for Bunting on stand C4-106 at Cenex-LCV (UTAC Millbrook Proving Ground, Bedfordshire, UK, 23rd to 24th September 2021). In particular focus is the technique of magnetizing magnet assemblies after construction, which offers a wide range of benefits including accuracy and safety. The LCV…
Read MoreMagnetiser and Magnet Setter Export Success
Successful implementation of an overseas business development strategy has resulted in orders from Italy for a bespoke Industrial Magnetiser, complete with control cabinet, and a Magnet Setter. Bunting’s UK engineering design team will design, build and test the magnetisers, control and magnet setter. Industrial Magnetisers and Magnet Setters enable the charging of both permanent magnets…
