磁场变动 meaning in Chinese
field variation
Examples
- The core - mantle boundary is the closest researchers can get to the much more intense and complicated magnetic field that exists within the core , where magnetic fluctuations actually originate ; strong electric currents in the core prevent direct measurements of the magnetic field there
地核内具有更为剧烈、复杂的磁场，而且也是磁场变动的真正发源处，但是研究人员可推算的极限是在地核?地函交界处；因为地核内的电流极强，因此无法直接测量内部的磁场。
