Today we’re going to hear five marvelous facts about magnets fact number one. Magnets always have two poles the poles in a magnet are the sides or ends of the magnet where the magnetic field is strongest. The magnetic field is an invisible force around the magnet which is what causes the magnetic effect. Each magnet has a positive and negative pole. If you’ve cut a magnet in half, it will turn into two smaller magnets with the North and South Pole. These different poles react differently to Magnetic substances because of how the electrons in a magnet interact with materials.
Fact number two compasses work because of magnetism. The earth’s core is magnetic. And so the earth works like a giant magnet. This means that the Earth has a negative or North Pole and a positive or South Pole because of the effect of the Earth’s magnetism. We can use smaller magnets to find out where we are a compass is made up of a magnetic needle which balances on a short pin the magnetic needle will always point to Magnetic North if you know which direction you’re meant to be going and you know, we’re North is you will never get lost when using a compass.
It is important to keep away from other magnets or magnetic fields because they will throw off the compass and you might get lost Fact number three some magnets can be turned on and off these types of magnets are called electromagnets. They create magnetism when electricity flows through the metal electromagnets are used in lots of different things like phones radios doorbells and burglar alarms. One of the things electromagnets are best for is lifting very heavy metals in scrap yards when these powerful magnets are attached to cranes.
They can be used to lift. Lots of scrap metal to be recycled into new Metal Products. This magnet can stay off until it’s in the right place then be turned on to look lots of heavy scrap metal. Fact number four opposite magnetic poles attract. If you play with two magnets, you will notice they stick together that is because magnets are magnetic. However, if you flip the magnet, so two positive poles or two negative poles are facing each other. They will not stick together. The two magnets will even push away from each other.
So they’re further apart. This is because only opposite magnetic poles attract and stick together. Some metals will also be attracted to magnets and so magnets can stick to them. The main magnetic metals are iron nickel and Cobalt you can easily test if a metal is magnetic by checking if a magnet sticks to it try it using a fridge Magnet or other magnets that you have around the house. Fact number five magnets were used in ancient China Normal magnets are not made by people. So they naturally occur in nature lodestone is a natural magnet, which is created when magma cools down very slowly an ancient China people created the first ever Compass using lodestone and iron in a bowl of water. This technique was also used by some of History’s Greatest explorers the Vikings. I hope you enjoyed my five marvelous magnet facts. See you soon.
