The application of magnetic materials in the military field
Magnetic materials that are offered by magnetic products factory also have been widely applied in the military field. For example, ordinary mine or mines will explode only in contact with the target, so its role is limited. And if the magnetic sensor installed in the mine or mines, tanks, or warships are steel manufacturing in their proximity to the target (without contact), the sensor can detect magnetic field changes the mines or mine explosions, and improve lethality.
In the modern war, air supremacy is one of the keys to win the battle. However, during the flight, the aircraft is easy to be detected by enemy radar, which has a large risk. In order to avoid enemy radar surveillance aircraft, it can be coated with a layer of special magnetic materials - absorbing materials. It can absorb radar electromagnetic waves emitted by the radar, which makes radar waves rarely reflected, enemy radar can not be detected radar echoes and find the aircraft. This allows the aircraft to reach the purpose of stealth.
