地磁场的磁感线的分布比较抽象,地磁场中的电磁感应问题对于高中生来说一直是一个难点,下面就一道题目的分析来剖析地磁场中的电磁感应问题。如图所示为地磁场磁感线的示意图,在北半球地磁场的竖直分量向下。飞机在我国上空匀速巡航,机翼保持水平,飞行高度不 The distribution of magnetic induction lines in geomagnetic field is rather abstract. The electromagnetic induction problem in geomagnetic field has always been a challenge for high school students. The following analysis of a topic analyzes the electromagnetic induction problem in the geomagnetic field. As shown in the diagram of the magnetic field of the earth’s magnetic field, the vertical component of the earth’s magnetic field in the northern hemisphere is downward. The aircraft cruised at constant speed over our country, the wings remained level, and the flight altitude was not
