| 单词 | Larmor precession |
| 释义 | Larmor precession A precession of the motion of charged particles in a magnetic field. It was first deduced in 1897 by Sir Joseph Larmor (1857–1942). Applied to the orbital motion of an electron around the nucleus of an atom in a magnetic field of flux density B, the frequency of precession is given by eB/4πmυµ, where e and m are the electronic charge and mass respectively, µ is the permeability, and υ is the velocity of the electron. This is known as the Larmor frequency |
