Why rare-earth magnets work
Jon Titus   3/5/2012 1:18:34 PM

Wikipedia has an interesting submission that explains why these rare-earth magnets exhibit such good magnetic properties:http://en.wikipedia.org/wiki/Rare-earth_magnet.  The US Geolgical Survey offers an interactive map that shows worldwide mines, deposits, and occurrances or rare-earth minerals: http://mrdata.usgs.gov/mineral-resources/ree.html.  You'll see that rare-earth minerals are not particularly rare, although it's rare to find sites for economical mining.

What about Australia?

Nice article, Kristen. And it's an important subject. I know Molycorp had come back online -- now that rare earth elements command a significant price again, but I didn;t realize that dysprosium would not come online for years yet. I know Australian mines have come back online. Will Australia help with some of these shortages?

Shortages seems to be new reality, so now what?

Kristen, thanks for the overview on rare earth metals and specifically the background on what's causing the shortages. I think the three scenarios you keyed in on at the end of your post could be really instrumental for engineers looking for alternatives to these materials or at least a strategy for lessening their dependence on them for their designs. Given the state of the world economy and global tensions, constant price spikes seem to be the new order. I'm sure I speak for our audience when I say I'd love to hear more about each of those three strategies and I'm hoping subsequent posts in your series hit on these tactics.

According to a study by the National Institute of Standards and Technology, one of the factors in the collapse of the original World Trade Center towers on Sept. 11, 2001, was the reduction in the yield strength of the steel reinforcement as a result of the high temperatures of the fire and the loss of thermal insulation.

Robots are getting more agile and automation systems are becoming more complex. Yet the most impressive development in robotics and automation is increased intelligence. Machines in automation are increasingly able to analyze huge amounts of data. They are often able to see, speak, even imitate patterns of human thinking. Researchers at European Automation call this deep learning.
