Magnets can be divided into "permanent magnets" and "non-permanent magnets". Magnets are composed of atoms such as iron, cobalt, and nickel. The internal structure of the atoms is quite special. They have magnetic moments and can generate magnetic fields. Is it normal for stainless steel to attract magnets? Please continue reading!

The role and function of magnets

Magnets have the property of attracting ferromagnetic materials (such as iron, nickel, cobalt and other metals), and are mainly used in traditional industry, medicine, astronomy, and military fields. Magnets can generate magnetic fields. The earliest "compass" was made using magnets, which is of great significance to human development.

The components of magnets are atoms such as iron, cobalt, and nickel. The internal structure of these atoms is quite special and they have magnetic moments themselves and can generate magnetic fields.

Magnets can be divided into "permanent magnets" and "non-permanent magnets". Permanent magnets are also called natural magnets and can also be artificially made. Non-permanent magnets only show magnetism under certain conditions and are usually produced in the form of electromagnets.

The earth is also a large magnet, with its two poles located close to the geographic South Pole and the geographic North Pole. When the magnets on the surface of the earth can rotate freely, they will indicate north and south due to the property of like poles repelling each other and opposite poles attracting each other.

Is it normal for stainless steel to attract magnets?

It is normal for stainless steel to attract magnets. Stainless steel may become magnetic due to fluctuations in its chemical composition or different processing conditions during the smelting process. Stainless steel is the abbreviation of stainless acid-resistant steel, which is a type of steel that is resistant to weak corrosive media such as air, steam, and water or has stainless properties.

The corrosion resistance of stainless steel decreases as the carbon content increases.

Metal wire mesh such as stainless steel mesh is mainly used for screening and filtering in acid and alkaline environments.

Stainless steel is used in heavy industry, light industry, daily necessities industry, building decoration and other industries.

Can cans be attracted by magnets?

Cans are generally divided into aluminum cans, alloy cans, and iron cans. Aluminum cans will not be attracted by magnets, but some alloy cans may be attracted by magnets. Aluminum is a paramagnetic material that has no magnetic field and will not be attracted by magnets. Alloys are mixed metals, and whether they will be attracted by magnets depends on the metal content in the alloy. Pure iron cans will be attracted by magnets.

Iron cans are more expensive, and in order to control costs, most beverage manufacturers generally do not choose to use iron cans to package their drinking products.

Generally, you can distinguish iron cans from aluminum and alloy cans by their weight. Iron cans are heavier than aluminum and alloy cans.
