Definition form Wikipedia: A degauss causes a magnetic field to oscillate rapidly, with decreasing amplitude.
摘自维基百科的定义:消磁产生幅度递减的快速交变磁场。
The temperature at Earth's exobase oscillates but is typically about 1,000 kelvins, implying that hydrogen atoms have an average speed of five kilometers per second.
