What is the principle of electromagnetic gun firing shells?

The principle of electromagnetic gun firing shells is Lorentz force.

Electromagnetic gun is an advanced kinetic energy killing weapon made by electromagnetic emission technology. Different from the traditional gun which exerts the pressure of gunpowder gas on the projectile, the electromagnetic gun uses the Lorentz force generated by the electromagnetic field in the electromagnetic system to accelerate the metal projectile to achieve the kinetic energy needed to hit the target. Compared with the traditional gunpowder-driven gun, the electromagnetic gun can greatly improve the speed and range of the projectile.

Use:

(1) Used in space-based anti-missile system: Due to its extremely high initial velocity, electromagnetic guns can be used to destroy low-orbit satellites and missiles in space, and can also intercept missiles launched by ships and armor.

(2) Used in air defense system: Due to the high muzzle velocity of electromagnetic gun, the firing rate is also high. Some American military experts believe that electromagnetic guns can replace air defense weapons and missiles to perform air defense tasks.

(3) Used as anti-armor weapon: American shooting test proves that electromagnetic gun is an effective means to deal with tank armor. The projectile with a mass of 50g and a speed of 3km/s is an excellent anti-armor weapon.

(4) Used for refitting conventional artillery: With the development of electromagnetic launching technology, installing electromagnetic acceleration system at the muzzle of ordinary artillery can greatly improve the range of artillery.

(5) Anti-tank weapons. Due to the high muzzle velocity, the electromagnetic gun has strong armor-piercing ability, which can effectively penetrate the tank armor and become an anti-tank weapon.

(6) Used to equip artillery units. Electromagnetic guns are expected to be equipped with artillery units.

(7) Used to equip naval vessels. Due to the characteristics of electromagnetic gun, it is expected to replace artillery and become a new type of naval gun equipped with naval vessels.
