| 单词 | ring current |
| 释义 | ring currentring currentAn electric current flowing westward around the Earth; it arises from a net eastward flow of electrons and a net westward flow of protons trapped inside the Van Allen radiation belts. The current produces a magnetic field that cancels part of the geomagnetic field at the Earth's surface. During geomagnetic storms, when the Van Allen belts are recharged with particles, the increased ring current results in a further decrease of the Earth's surface magnetic field strength.ring current[′riŋ ‚kə·rənt] |
