How do you close the door of your room? You either close the latch or rotate the door knob. Is that the same way you close your refrigerator door? Does it have a latch? No, right? Then how does it close?
A fridge has a magnet on its side. The refrigerator door sticks to the magnet when you close it.
Where else do you use or find a magnet?
Magnets are used in your computers, pencil-box, toys, and in the kitchen, like fridge magnets. Magnets are so freely around us that we do not always realize using them.
So much magnet around us, do you know where these many magnets come from?
They come from China. Almost 90% of magnets come from China, but were not discovered there. Here’s the interesting story behind the discovery of magnets.
Once there was a Greek shepherd named ‘Magnes’. One day, he took his sheep over the mountains of ‘Magnesia’. Suddenly, his foot and stick got fixed to the ground. He tried hard to lift both but he could not. Just then he realized that the nails and buckle of his sandals and the iron tip of his stick were fixed to a big stone. The stone was not ordinary.
This special stone was called ‘Magnetite’ or Lodestone. It had a magical power of attracting things that were made of iron. This was how a natural magnet was discovered. Now, can you relate to its name with the mountains and the stone? This is how people found magnet and named it so.
Magnets come in different shapes. Bar magnets, cylindrical magnets, horseshoe magnets, ring magnets, and ball-ended magnets are a few examples. Magnets were first discovered in Greece.
However, Chinese scientists had invented the magnetic compass. The compass needle points in the North direction. It is used by sea travelers when they get lost.
