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。

For example, if we talk about photons, of course, we also just mean light, sometimes we refer to this as electromagnetic radiation, and there's several ways that you might be asked this in a problem or that you might be asked to answer.

举例来说，如果我们讨论光子，当然我们也叫做光，有时候我们看作是电磁辐射，而且这里有几种方式,你可能会在题目中被问到,或者被提问回答。

Unlike other e-book devices, Samsung's E6 and E101 enables handwriting directly onto the display, allowing users to annotate their reading selections, calendars and to-do lists with a built-in electromagnetic resonance (EMR) stylus pen.

However, because of a different system of electricity supply in the UK, electromagnetic fields are generally less intense, resulting in only a few children found to be exposed to levels greater than 0.2 micro-Tesla.
