Now consider applying an external magnetic field to the hydrogen atom. 現在考慮加一外磁場(chǎng)于氫原子。
In other words, each domain is spontaneously magnetized to saturation even in the absence of any external field. 換句話(huà)說(shuō)，即使在沒(méi)有任何外磁場(chǎng)的情況下，每個(gè)磁疇也自發(fā)地磁化到飽和。
When exposed to an external magnetic field, these spinning "bar magnets" attempt to align their axes along the lines of magnetic force. 當這些自旋的磁鐵棒暴露在外部磁場(chǎng)中時(shí)，它們就試圖將自己的軸線(xiàn)按照磁場(chǎng)力的方向排成直線(xiàn)。
