当一个物体放旋转时,它就可能带上了电荷,或者形成微弱的电流,这是有事实根据的,如我们的栖息地地球,由于它质量大和它的自转速度快,在它的经度线上就形成了一条自东向西的电流,形成了南北磁场,也就是我们所说的南北极。我想对于这样大的质量球体,在它旋转时,它外部和内部的速 When an object is rotated, it may be charged, or form a weak current, which is based on facts, such as our habitat Earth, because of its mass and its rapid rotation, in its longitude line On the formation of a current from east to west, formed a north-south magnetic field, which is what we call the North and South Pole. I think for such a large mass sphere, when it spins, it’s outside and inside
