Magnets cannot attract electricity.
The components of magnets are atoms such as iron, cobalt, and nickel. The internal structure of the atoms is relatively special and they have magnetic moments themselves. Magnets can generate a magnetic field and have the property of attracting ferromagnetic substances such as iron, nickel, cobalt and other metals.
Types of magnets:
1. Shape magnets: square magnets, tile-shaped magnets, special-shaped magnets, cylindrical magnets, ring magnets, disc magnets, bar magnets, magnets rack magnet.
2. Attribute magnets: samarium cobalt magnets, neodymium iron boron magnets, ferrite magnets, alnico magnets, iron chromium cobalt magnets.
3. Industrial magnets: magnetic components, motor magnets, rubber magnets, plastic magnets, etc. Magnets are divided into permanent magnets and soft magnets. Permanent magnets are added with strong magnetism to align the spin of the magnetic material and the angular momentum of the electrons in a fixed direction. Soft magnets are added with electricity.

Applications of magnets:
Magnetic materials are also widely used in the military field. For example, ordinary sea mines or land mines can only explode on contact with the target, so their effectiveness is limited. And if a magnetic sensor is installed on a mine or landmine, since tanks or warships are made of steel, when they approach, the sensor can detect changes in the magnetic field and cause the mine or mine to explode, increasing the lethality.
In modern warfare, air superiority is one of the keys to winning a battle. However, the aircraft is easily detected by enemy radar during flight, which poses a greater risk.
