| 单词 | magneton |
| 释义 | magneton A unit for measuring magnetic moments of nuclear, atomic, or molecular magnets. The Bohr magneton µB has the value of the classical magnetic moment of an electron, given by µB = eh/4πme = 9.274 × 10-24 A m2 , where e and me are the charge and mass of the electron and h is the Planck constant. The nuclear magneton , µN is obtained by replacing the mass of the electron by the mass of the proton and is therefore given by µN = µBme/mp = 5.05 × 10-27 A m2. |
