Military applications of magnetic field magnetic field of the same in the military has been widely used. For example, ordinary mines or mines explode only when in contact with the target triangle magnet, so a limited role. If the magnetic sensor is installed on a mine or mines, tanks or warships are due to magnetic steel manufacturing tools in their proximity (without touching the target), the sensor can detect changes in the magnetic field of the magnet so that mine or mine explosions, improved lethality. In modern warfare, the battle to win control of the air is one of the key to victory. But the aircraft during flight is easy to detect by enemy radar, which has a greater risk. In order to avoid enemy radar monitoring aircraft surfaces can be coated with a special magnetic material - absorbing material, which can absorb electromagnetic waves emitted by the radar, making radar aircraft touched electromagnetic waves occur after only a few reflections, so the enemy radar can not detect radar echoes, can not find the aircraft, which makes the aircraft reached a stealth purposes. This is the famous "stealth aircraft." Stealth technology is a hot topic in the world in the field of military research. American F117 stealth fighter is an example of the successful application of stealth technology. In the US "Star Wars" program, there is a new type of weapon "Electromagnetic weapons" research and development. Is the use of conventional artillery ammunition explosion instant expansion thrust generated when the shells quickly accelerate the introduction of bore. The guns are the shells on the solenoid, the solenoid is energized, the magnetic field generated by the solenoid on the shells will have a huge impetus to the shells fired. This is called the guns. There are similar electromagnetic missiles. Classification magnet, the magnet can be grouped into "permanent magnet" and "non-permanent magnets." The permanent magnet may be a natural product, also known as natural magnet luggage magnet to be manufactured by a human (the strongest magnets are neodymium magnets). The non-permanent magnet, and only under certain conditions be magnetic, usually in the form of an electromagnet to produce, that is, using a current to strengthen the magnetic field.
