7 Lesser Known Applications of Rare Earth Permanent Magnets

Earlier today, I posted an article over at RareMetalBlog after the question of non-defense applications of rare earth permanent magnets came up. Certainly most of us are aware of the use of such materials in motors and generators, but there are hundred of other applications for such magnets – and not just in the form […]

I have just uploaded the pre-print of a new white paper titled “Running the Gauntlet: Rare Earths, Specialty Metals and Turf Wars Within the Beltway“. I started work on this after discovering that rare earth materials feature prominently in current legislation going through the US Congress.  Posted below are the first few paragraphs of the […]

Google Shines A Light On Hans Christian Oersted

It was interesting to see that Google today honored the birthday of Hans Christian Oersted, with one of their famous Google doodles.  Outside of the magnetics world, Oersted is probably not as well known as individuals like Michael Faraday and Nikola Tesla, and yet he is one of the founding fathers of electromagnetism. Oersted was […]

How To Convert Atomic Percent To Weight Percent And Vice Versa

In the course of reviewing information on metals and minerals, I often come across chemical composition information that is written in terms of atomic percent, when I am actually more interested in the weight percent values of the elements involved.  A little less frequently I want to do things the other way around, and do […]

New Mixed Rare Earth Permanent Magnet Material Shows Promise

Recently I came across a May 2009 presentation published by the US Department of Energy’s [DoE] Ames Lab, on a new mixed rare earth-based [MRE-Fe-B] permanent magnet [PM] alloy, for high temperature applications. The work forms part of the DoE’s multi-year FreedomCAR project, with a number of specific goals: Production of magnet materials for PM […]

How Does The Use Of Permanent Magnets Make Wind Turbines More Reliable?

For all of its soaring elegance, it is easy to forget just how complex a machine the modern-day commercial-scale wind turbine really is.  In this article I will focus on the massive, highly engineered electromechanical system sitting at the top of every wind turbine tower.  We’ll explore how the use of permanent magnets in the […]

Why Are Wind Turbines Getting Bigger?

No-one following the growth of the wind turbine industry over the last two decades will have failed to have noticed the trend towards larger and taller turbines.   While this might seem to just be the natural order of things [after all, "bigger is better", right?] – it might be a useful exercise to pause […]
