反磁性
某些材料被磁鐵輕微推開的現象
the weak effect in which some materials, such as copper, are pushed away from a magnet instead of being pulled toward it.
Nikos learned that diamagnetism makes a copper coin move slightly away from a strong magnet.
Nikos 學到，反磁性會讓銅幣稍微遠離強力磁鐵。
diamagnetism + makes + object + move away from a magnet
Unlike iron, copper shows diamagnetism, so a magnet cannot pull it closer.
和鐵不同，銅具有反磁性，所以磁鐵無法把它吸近。
contrast: iron is pulled, copper shows diamagnetism
In class, Layla measured the tiny diamagnetism of a bismuth sample.
上課時，Layla 測量了一塊鉍樣本微弱的反磁性。
Because of diamagnetism, the piece of bismuth was pushed gently away from the magnet.
由於反磁性，那塊鉍被輕輕推離了磁鐵。
Because of diamagnetism + passive: be pushed away from
Diamagnetism is much weaker than the pull a magnet has on iron.
反磁性比磁鐵對鐵的吸力弱得多。
