					Magnetic movements


In the rest of the world, scientists are exploring many avenues,
including improvements in today's NdFeB magnets. One option: To cut the
amount of dysprosium, another rare-earth metal used in the magnets.
Scientists found that putting dysprosium only at the boundaries between
the grains in the magnet is enough to do the trick. The University of
Tohoku and Intermetallics Co. Ltd in Japan, as well as companies such as
Siemens AG in Germany, are searching for ways to apply dysprosium in just
those spots.

As scientists around the world search for a path to independence from
rare-earth metals, they each hope for their own magnetic moment. If their
efforts hold charge, they'll be able to power new industries—and maybe
even a little world trade peace.
