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.
