On June 17, 2025, a J-35 stealth fighter, propelled by an electromagnetic catap, shot off the deck of the Fujian aircraft carrier like an arrow from a bow, accelerating to 240 kilometers per hour in the blink of an eye. 

    people can't help but wonder: What exactly is electromagnetic launching? Why is it so powerful? The essence of electromagnetic launching is the application of the principle of electromagnetic induction discovered Faraday in 1831, condensed into a track on the deck that is only a hundred meters long. When current flows through the linear motor coil, the thrust generated the magnetic field is transmitted through a "back-and-forth carriage" to push the aircraft, accelerating it to takeoff speed within 2.5 seconds. The principle is to that of magnetic levitation trains. Compared with traditional steam catapults, electromagnetic catapults have the advantages of small volume, low requirements for auxiliary systems on ship, high efficiency, light weight, and low operation and maintenance costs. It is one of the core technologies of future aircraft carriers. For example, the USS Ford, commissioned by US Navy in 2013, uses a linear motor electromagnetic catapult. With the rapid development of linear motors, they are gradually being reused in the field, such as electromagnetic catapults, military target ranges, and military simulation systems.
