英语词汇“gyromagnetic ratio”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

1. Physics. Of or pertaining to the interdependence of the angular momentum of a spinning charged particle and its resulting magnetic moment; gyromagnetic effect: any effect arising from this interdependence, esp. the fact that a change in the angular momentum of a freely suspended magnetizable body will produce a change in its magnetic moment, and vice versa; gyromagnetic ratio: the ratio of the angular momentum of a spinning charged particle to its magnetic moment; also, the reciprocal of this, expressed either as a true ratio (symbol γ) or as a dimensionless quantity (symbol g′).
