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…

Neodymium Price Trends

Updated 25 January 2022 In 12 months, since January 2021, the price of Neodymium has doubled, exceeding 1,200,000 CNY/T. The price has increased by 2.6 times since May 2020, when the price started to increase (Trading Economics). Short and long term price projections remain uncertain. Magnet & Magnet Assembly Design At Bunting, the focus is…

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…

Permanent Magnet Motors Providing Key Benefits

White drone motor close up on a black background

Permanent magnet motors are electric motors using permanent magnets in addition to windings.  Such motor designs are more efficient than induction motors or motors with field windings for certain high-efficiency applications such as electric vehicles and small electric motors such as found on drones and in car windshield wipers. Both AC and DC motors benefit…
