The word magnet came from the name of a Greek shepherd, Magnes, who discovered that a certain rock in the ground attracted certain metals. The legend says that the shepherd was herding his sheep when the iron nails in his sandals mysteriously stuck to a rock in the ground. When he picked up a similar rock and brought it back to his town, everyone thought the rock possessed some sort of magic and that is why it “loved” the iron. The rock that he found was called magnetite, or lodestone. Lodestone is a type of iron ore that has magnetic attraction, although rarely does it possess a strong magnetic field. There are many other cases of incidents that have happened with natural magnets to unsuspecting people. In one case, a miner had his metal helmet pulled off hi

Magnets have many uses in the world today from showing which way is north and south, to cooling you off by a fan. The oldest record of a significant use of the magnet is by the Chinese who made the first compass, and used it in their travels. An important thing to remember about magnets is the like poles repel each other. Many inventors have used this fact to create new inventions, or to improve old ideas. For example, in some places they have tested the idea of putting magnets that repel each other on the bottom of a train and on the tracks instead of wheels to allow the train to travel. Because the two magnets repel each other, the train glides across the track with out causing any friction. In the future we may reduce the use of tires and replace them with repelling magnets.

In the future many things may be positively affected by the use of magnets. Many things could be made better and safer by properly applying the concepts in this paper, and money and time may be saved by not having to replace or repair parts.

The science fair project that will be conducted will test the differences between magnet, electromagnetic, and spring shocks. When opposite poles are facing each other magnets, like springs, push outward when pressure is applied to it. My Project will test the performance of the three shocks by the consistency in the amount of p
