Magnetic applications in the aircraft field
Magnetic materials are also widely used in the military field. For example, ordinary mines or mines can only explode when in contact with a target, so the effect is limited. If magnetic sensors are installed on mines or mines, because tanks or warships are made of steel, the sensors can detect changes in the magnetic field to explode mines or mines when they are close (without touching the target), increasing the lethality.
In modern warfare, air superiority is one of the keys to winning the battle. However, the aircraft is easily detected by the enemy's radar during the flight, which is of great danger. In order to avoid the monitoring of enemy radar, a special magnetic material-absorbent material can be coated on the surface of the aircraft, which can absorb the electromagnetic waves emitted by the radar, so that the radar electromagnetic waves rarely reflect, so the enemy radar can not detect the radar echo. Can not find the aircraft, which makes the aircraft reach the purpose of stealth. This is the famous "stealth aircraft." Stealth technology is a hot spot in the world of military research. The US F117 stealth fighter is an example of the successful use of stealth technology.
