本周我们学习了磁铁的两极，我们可以将磁铁分为南极和北极。通过实验探究了

This week we learned about the two poles of magnets. We can divide magnets into south pole and north pole. Through experiments, it is explored that the magnetic force of each part of the magnet is different. According to the number of iron needles attracted by the magnet, it is concluded that the two poles of the magnet have the largest magnetic force, and the central part has the weakest magnetic force.

This week we learned about the poles of magnets, which we can divide into the South Pole and the North Pole. Through experiments to explore the magnet's various parts of the magnetic force size is not the same, according to the number of magnets to attract iron needles to obtain the magnet's polar magnetic force is the largest, the middle part of the magnetic force is the weakest.
