Because moving charges make currents, and changing magnetic fluxes breed voltages, the new device would generate a voltage from a current rather like a resistor, but in a complex, dynamic way.

因为移动的电荷会产生电流，变化的磁通量会产生电压，新的设备会从电流中产生电压，像电阻一样，不过是以更加复杂、动态的方式。

And a group of them have now taken a step towards developing such a piece of kit-a magnetic memory with no moving mechanical parts.

如今已有一批工程师们开始着手研发这样的一款设备—没有机械运动部件的磁性存储器。

Large stars end in the more spectacular explosions known as supernovae, which generate fast-moving particles in extraordinarily high magnetic fields.

At least those old news reels had traces of the audible static of old magnetic sound recording to remind you that the pictures in front of you were actually moving.

The radiation belt, which contains "two concentric rings of charged particles trapped by Earth's magnetic fields" doesn't affect current astronauts going to and from space because they are moving too fast to be hit by the radiation.
