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…

Ferrite Magnet Price Concerns

Ferrite & Strontium Prices

The latest magnet material with pricing concerns (Neodymium Price Concerns – June 2021) is Strontium Ferrite. The Strontium Ferrite (SrFe12O19) magnet is the most commonly used magnet material, featuring in switches, electric motors, telecommunications, and electronics.  Strontium hexaferrite’s hard magnet material has a high coercivity due to its magnetocrystalline anisotropy.  The material’s resistance to corrosion…

Neodymium Price Concerns

Neodymium Prices Combo

The price of Neodymium reached a 9-year high in March 2021, rising by 42% since the beginning of the year (Trading Economics).  Although the price has dropped slightly since the peak (as of early May 2021), the projected price trend in the short and long term is uncertain. Magnet & Magnet Assembly Design At Bunting,…

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…

Rare Earth Magnets in Electric Vehicle Motors

Electric Vehicle Plugged in and charging

The global move towards the electrification of vehicles continues to gather momentum.  In 2010, the number of electric cars on the world’s roads reached 7.2 million, of which 46% were in China (iea.org/reports/global-ev-outlook-2020).  By 2030, the number of electric cars is expected to swell to 250 million, a massive growth in a relatively short time.…
