Sagawa began working on permanent magnets when his employer ... but it lacked a sufficient coercivity — a measure of a magnet’s resistance to other strong magnetic fields,” explains Sagawa.

The new material was another breakthrough—a permanent magnet with higher coercivity, a measure of a magnet's ability to withstand an external magnetic field. The best permanent magnets used in ...
