Recent Developments in Permanent Magnet Gear Systems & Machines

Last month I attended the Magnetics 2010 Conference in Florida, where a variety of speakers gave updates on the business and technical side of the magnetics industry. One of these days I’ll actually write up my thoughts on the conference itself, probably in conjunction with my RareMetalBlog parter in crime, Ian London. In the meantime, […]

The Concerted European Action On Magnets: A Model For Facing The Rare Earths Challenge?

Wednesday, February 10, 2010

2 Comments

In 1984, the magnetic materials research community in Europe was at a formidable crossroads. The latter part of 1983 had seen industrial research groups in the USA and Japan simultaneously announce the discovery of a promising new permanent magnet material, based on the neodymium-iron-boron [Nd-Fe-B] alloy system. This long-sought successor to the ever more expensive […]

Magnetic Tape Gets A Boost

Earlier this week, MIT’s Technology Review published a story on a new magnetic tape material which, combined with a novel tape-reading technology, can produce data storage capacities of 35 Tb per cartridge – over 40 times higher than current tape storage systems. The research was conducted at IBM’S Zurich Research Labs in Switzerland, in conjunction […]

You may recall an article I wrote late last year on Correlated Magnetics Research, a company from Alabama who has created and produced what they were calling “programmable” magnets. Since then, I’ve had the chance to play with a number of their prototypes.  I had initially been a little confused as to what the technology […]
