In a superconductor, magnetic flux is quantized in units of the magnetic flux quantum.
在超导体中,磁通量以“磁通量子”为单位呈量子化分布。
SQUID sensors detect extremely small magnetic fields by measuring changes of flux in fractions of a magnetic flux quantum.
SQUID(超导量子干涉器件)通过测量相当于磁通量子分数的磁通变化,来探测极其微弱的磁场。
词源 Etymology
magnetic 源自希腊语 *magnētis (lithos)*,意为“马格尼西亚之石/磁石”,后演变为“磁的”。
