The Frontier of Magnet Research

Used in cellphone speakers and computer hard drives, neodymium magnets are indispensable to today's high-tech devices. We visited the development site of a magnetic refrigerating device to learn more about the new method it uses. We also have the latest news on a national project headed by Doctor Sagawa, the inventor of the neodymium magnet, to reduce the need for a rare earth called dysprosium. Japan has always been at the forefront of magnet research and today we'll be visiting the frontlines!
