地球是个大磁体,在地球的周围空间充满了地磁场,地磁场的南极在地球的北极附近,地磁场的北极在地球的南极附近.正是由于这个原因,使得同学们在遇到与地磁场有关的问题时常常出错.下面举例说明,希望对同学们熟记地磁场的基本知识能够有所帮助.一、猜想地磁场的产生例1根据安培的设想,认为磁场是由于运动电荷产生的.这种思想对于地磁场也适用,而目前地球上并没有发现相对地球定向运动的电荷,由此可知
Earth is a large magnet, the Earth’s surrounding space is filled with the Earth’s magnetic field, the South Pole of the Earth’s magnetic field near the Earth’s Arctic and the North Pole of the Earth’s magnetic field near the Earth’s Antarctic It is precisely for this reason that students are faced with the Earth’s magnetic field The following problems are often mistaken: The following examples illustrate that I hope students will be able to memorize the basic knowledge of geomagnetic field can help I. First, guess the magnetic field generated Example 1 According to Amper’s idea that the magnetic field is due to the movement of charge generated. This idea is also applicable to the geomagnetic field, and at present there is no charge on the earth that is orientated relative to the earth,
