地球内核的外水圈隐藏着巨大的吸引力,这是因为地球本身就是个大磁场。加拿大地质调研所的地质专家兰迪·恩肯博士认为,距离地球表面3000公里深处的水圈是沸腾、滚烫的镍、铁等物质,而这恰恰创造了犹如电子穿过电线圈的磁场。兰迪解释道:“地球内部的磁场看起来就像一根磁棒插在地球中央。”指南针总是指向北方,正是因为磁场都是由南向北方向运动的。 The outer circle of the Earth’s inner core hides a huge attraction because Earth itself is a large magnetic field. According to Dr. Randy Enken, a geologist at the Geological Survey of Canada, the water circle 3,000 kilometers deep from the surface of the earth is boiling, hot nickel, iron and other substances, and this just created a magnetic field like electrons passing through the electric coil. Randy explained: “The magnetic field inside the Earth looks like a magnetic rod inserted in the center of the earth.” The compass always points north, precisely because the magnetic field moves from south to north.
