In our life, magnets are common magnetic substances. We've all seen and played with magnets and experimented with them in physics class. The makers of aluminium and cobalt magnets argue that magnetism is natural, not human. The stone absorbs some of the iron content easily, and it feels like magic. When early navigators discovered its function, they used it as a simple compass to find the direction of the sea. In fact, its scientific name is magnet, which has a special atomic structure. The ends of a magnet are called poles. The first is magnetism, which creates a magnetic field that attracts ferromagnetic materials. What is a ferromagnetic substance? Like iron, when there's no magnetic field inside the atom, it's out of order, and the magnetic forces cancel each other out. When in contact with a block of iron, the atoms inside line up under the action of a magnet and are attracted to it. Can magnets absorb everything? The answer is no, as with copper, which is diamagnetic and repels in a magnetic field.
In addition, aluminum is not attracted to magnets and is a paramagnetic material. There's almost no magnetic field in there. Although the magnet will generate a certain magnetic field, but the field is very weak, less than a tenth of the iron, so it will not be attracted to the magnet. Manufacturers of aluminium and cobalt magnets say this also explains why aluminium POTS cannot be used in induction stoves.
Therefore, magnets can attract ferromagnetic materials such as iron, but cannot attract paramagnetic and diamagnetic materials such as aluminum and copper. Aluminum cobalt magnet manufacturers remind, in the choice of magnets, of course, also want to consider its shape, including bar, round, tile and other shapes.
In fact, magnets are used quite frequently in everyday life. For example, manufacturers of nickel-cobalt magnets used it to invent the compass, including magnetic therapy, which is also used in maglev trains. Therefore, magnets play an important role in traditional industry, medicine and the military. The earth is huge, and it contains many substances, each of which will eventually be needed by human beings.
