Over the past year, the price of neodymium has quadrupled, as electric motors and generators that use permanent magnets instead of electromagnetic windings in their rotors have proliferated.

去年，由于使用永磁体代替电磁线圈转子的电动马达和发电机数量激增，钕的价格也增长了三倍。

And, just like motors, artificial muscles can also be used in reverse as generators, transforming movement into electricity.

而且，如同电动机一样，人造肌肉还能反过来当发电机使用，将运动转化为电力。
