Bismuth, for instance, is diamagnetic, so it's always repelled by a magnet.

比如铋就具有逆磁性，所以它总是被磁体排斥。

Physicists have been able to levitate animals, like this frog using a high magnetic field as living things consist of diamagnetic molecules like water, proteins and bones and the tiny forces these molecules give off allow them to levitate.

物理学家们已经能够使动物悬浮起来，就像这只青蛙一样，利用高磁场悬浮起来一样，因为生物是由水、蛋白质和骨头等抗磁性分子组成，这些分子释放出的微小力能使它们悬浮起来。
