electromagnetic launcher

An electromagnetic launcher uses powerful magnetic fields to accelerate objects, such as projectiles, to high speeds without traditional explosive propellants. It works by passing an electric current through coils around a tube, creating a magnetic field that pushes the object forward along the tube via electromagnetic force, a process called the Lorentz force. This technology allows for launching objects with greater speed and precision, often used in advanced military systems like railguns or for launching spacecraft. It offers a cleaner, more efficient alternative to chemical propellants, leveraging electricity and magnetism for rapid acceleration.
