Pushing the boundaries of magnet design
For physicists, loss of magnetization in permanent magnets can be a real concern. In response, scientists created the strongest available magnet -- one offering ten times more magnetic energy than previous versions -- in 1983. These magnets are a combination of materials including rare-earth metal and so-called transition metals, and are accordingly referred to as RE-TM-B magnets.
