（1）方法一：用磁铁和指南针吸.吸住指南针北极的那端是磁铁南极.吸住指南针南极
的就是磁铁北极.
方法二悬挂法.离磁铁较远处先用指南针判断方位.然后将磁铁悬挂.等待静止后观察磁
铁的朝向.
（2）相互吸引.因为磁铁具有异极相吸的性质.
（3）用一块Ａ去吸另一块Ｂ的中间.如果能吸住.Ａ为磁铁；如果吸不住.则Ａ为铁.

五、简答题：
1、答题要点：多数植物能自己制造“食物”——养料.满足植物生长的需要.这些养料是由植物绿色的叶依靠阳光提供的能量.利用二氧化碳和水制成的.这种作用叫做光合作用.用公式表示如下：
2、答题要点：共有二种方法.只要写出一种得十分.一、用线系住磁铁的中间.把它挂在空中.等静止下来.指南的一端是南极.指北的一端是北极.二、用一块已知南北极的磁铁的一个极去靠近.如果相吸.磁极正好相反；如果相斥.则磁极一样.。
