- When the sun's rotation sweeps this warped surface across the earth, we detect sudden changes in the polarity of the magnetic field. 当太阳的自转使这个波浪形间隔面扫过地球时，我们就会探测到磁场极性的突然反转。
- Under the same wavelength of light, the more intense the magnetic field strength, the larger the rotated angle of polarization of light. 在相同的磁场强度下,光波长越短,其电场振动面旋转角度越大。
