How are magnets made?

I don't know if anyone has had such an experience, which is that the thing they really enjoyed playing with in class when they were young was a magnet, and because magnets can attract iron or some metal products, they generate a certain amount of attraction, which also made us children who didn't have too many toys play with great fun when we were young. However, many people don't know how magnets are made? Today, the editor will show you how to make a magnet.

We all know that magnets are divided into permanent magnets and non permanent magnets. Generally speaking, what we often see is permanent magnetic magnets, while non permanent refers to some magnetic devices that only have magnetism under specific circumstances. Generally speaking, electromagnets are the most common.

Firstly, in the manufacturing process of magnets, the first step is casting. Copper, sulfur, nickel, iron, aluminum, and titanium metals are first melted into liquid in an electromagnetic furnace, and then the liquid is poured into the mold to create the approximate shape of the magnet. However, at this time, the magnet does not have any magnetism!

To make the magnet magnetic, the second step is to energize it, tie it to a copper tube and place it in a larger tube. Then, charge it with high voltage. At this time, the electrons in the magnet will slowly flow from the positive electrode to the negative electrode, causing a certain conversion efficiency of the electrons on both sides. This is precisely because after this step is completed, the magnet will have magnetism.

So after reading about the production methods of magnets, I believe everyone has some understanding that magnets are not easy to manufacture. Moreover, magnets now occupy a major position in more and more industries and infrastructure construction. Therefore, the research on natural magnetite is still under continuous efforts!
