My 12 year old had a lesson in his science course later that day that mapped magnetic fields of a little bar magnet.───当天的晚些时候，我12岁的大儿子在他的自然科学课上绘制了一幅磁铁的磁场分布图。

One of these was loadstone which is basically a chunk of naturally occurring iron which has somehow in the course of the earth’s long history obtained a magnetic orientation.───这些矿石中的一种负载石在漫长的地球演变过程中变成了具有磁场能力的块状的大型天然铁。

My 12 year old had a lesson in his science course later that day that mapped magnetic fields of a little bar magnet. He showed me the results.───当天的晚些时候，我12岁的大儿子在他的自然科学课上绘制了一幅磁铁的磁场分布图。他向我展示他的成果。
