The Metal Detector
Have you ever been to the beach? Did you see a man with a headset pointing a long pole at the ground? If so you might have seen a person using a metal detector. People use these devices to find metal.
Metal detectors make magnetic waves. These waves go through the ground. The waves change when they hit metal. Then the device beeps. This lets the person with the device know that metal is close.
The first metal detectors were meant to help miners. They were big and cost a lot of money. Although they used a lot of power, they didn't work well. People kept trying to make them better.
Gradually metal detectors got smaller. Now they are not only light and cheap. they also work better. That is why people bring them to the beach in order to look for their lost things like rings and bangles made of valuable metals. They can also look for phones in the sand. Metal detectors help them find these things.
Metal detectors also protect people. They help to keep guns out of important places. Like airports and courthouses. Some schools also use them. They help guards look for weapons. Guards use special wands to find metal on a person.
These devices save lives in other ways too. During wars, people plant bombs in the ground. When the war ends, they don't clean up their messes. This is unsafe for the people who live in those places. Others use metal detectors to find bombs. They remove them and help the people.
These devices also make clothes safer. It sounds funny, but it's true. Most clothes are made in big factories. There are lots of needles in these places. Needles break from time to time. They get stuck in the clothes. They would poke people trying them on. They don't though. That's because our clothes are scanned for metal. Isn't that nice? Thus metal detectors make the world a safer place.
