1英语翻译The Earth’s magnetic north pole is actually like the south pole of a magnet,and vice versa.译文:地球的磁北极实际上就相当于磁铁的南极,反之亦然.我认为地球的磁北极就是地球磁场的北极.换句话说,如果地球是一块磁铁,磁北极就应该是这块磁铁的北极.但为什么文章说“磁北极实际上就相当于磁铁的...
What causes the magnetic field of the earth? What is different about the magnetic poles of a common refrigerator magnet and the common bar magnet? How does the magnet attract something that is originally non magnetic? The south pole of a permanent magnet is attracted to a north...
Every magnet has a north pole and a south pole. Have you ever played with trains that have magnets? Sometimes, you try to put two train cars together, but push away from each other. Then you turn one of the cars around.The two cars attract each other rapidly. When the train cars ...
