I believe that many friends are very familiar with magnets, magnets have a lot of work, is a mutual repulsion and mutual attraction of the object. The magnet is composed of iron, nickel nie, cobalt gu, which has its own magnetic distance, and the internal structure is arranged in the same direction, one end of the North Pole and one end of the South Pole. So there are a lot of objects in nature, so why aren't they magnetic?

After making a sand mold in the shape of a magnet, materials such as copper, nickel, cobalt, sulfur and iron are placed in an electromagnetic furnace and heated to more than 1600 ° C, melting all metals into a liquid. When they are completely melted, the mixture is poured into the sand mold, and when the liquid is cooled, the primary material is obtained, which has no magnetic force.

Some people wonder how magnets are made and why they are magnetic. Years of doubt have been solved. As we all know, magnets are divided into permanent magnets and non-permanent magnets, let's take a look at permanent magnets, permanent magnets are able to maintain long-term magnetic and not easy to lose magnetic natural products, such as magnetite, to make this magnet.
