- When the sun's rotation sweeps this warped surface across the earth, we detect sudden changes in the polarity of the magnetic field. 當太陽(yáng)的自轉使這個(gè)波浪形間隔面掃過(guò)地球時(shí)，我們就會(huì )探測到磁場(chǎng)極性的突然反轉。
- Under the same wavelength of light, the more intense the magnetic field strength, the larger the rotated angle of polarization of light. 在相同的磁場(chǎng)強度下,光波長(cháng)越短,其電場(chǎng)振動(dòng)面旋轉角度越大。

- When the magma cools and solidifies, the direction and the polarity of the field are preserved in the magnetized volcanic rock. Reversals of the field give rise to a series of magnetic stripes running parallel to the axis of the rift. 巖漿冷卻并凝固下來(lái)后，地磁場(chǎng)的方向和磁極被保留在磁化了的火山巖中，磁場(chǎng)的逆轉形成一系列與斷層軸線(xiàn)平行的條形磁區。
