Rare earth magnets are now ubiquitous, being used in motors and actuators anywhere electricity is converted into motion. Examples range from motors in disc drives, moving both the disc and the read/write head, motors in portable power tools (drills, saws, drivers, etc...), remote door locks on cars. They touch every aspect of our modern technology. The material that enabled this revolution is the rare earth/iron compound Nd2Fe14B. This was discovered in the early 1980s as part of fundamental research on rapidly quenched liquid metals in which I was involved.

稀土磁铁现在无处不在，被用于电机和执行器，任何地方的电力转换为运动。例如磁盘驱动器中的电机，移动磁盘和读写头，便携式电动工具（钻头，锯子，驱动器等）中的电机，汽车上的远程门锁。它们涉及到现代科技的方方面面。促成这场革命的材料是稀土/铁化合物Nd2Fe14B。这是在20世纪80年代初发现的，作为我参与的快速淬火液态金属基础研究的一部分。
