See if you think magnets have surprising uses. Look closely and you will see. Magnets can be found in a fridge. The magnets attract (吸引) or pull the metal to make the door closed. Do you know how? A magnet pulls things made of metals called iron and steel. But it will not pull other things, such as a wooden pencil, a gold ring or a plastic toy, which means it does not attract all. Magnets can pull some things to them. Why is this true? The two ends of a magnet are its poles(磁 极). 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 they push away from each other. Then you turn one of the cars around. The two cars at- tract each other rapidly. When the train cars push away, two of the same poles are facing each other. However, if you put the north and south poles to- gether, they will be together at once. Scientists are using magnets in new ways. There is a new train that uses powerful magnets to travel more quickly. Magnets lift the train above the track(轨道) and push the train forward. The train appears to be moving as fast as wind! They are much faster than the trains we know. Besides, in medicine, the powerful magnets are used to help patients produce heat to kill cancer cells(癌细胞) without harming their body. The powerful magnets can also be seen in many fields, like space, indus- try, and teaching. So they play an important role in our life. 1.
