What Is an Electromagnetic Coil?

As shown in the figure, the electromagnetic coil gun (Electromagnetic Coil Gun) is a technical branch of electromagnetic emission. It usually consists of several coaxially arranged stator coils and an armature coil that can move axially inside it. The stator coils are charged in turn, forming a strong magnetic field around the coils, and interacting with the magnetic field of the armature induced (or externally input) current, generating Lorentz forces to drive the armature. Multi-stage stator coils are used to accelerate the armature in turn, and the armature can be continuously accelerated by accurately controlling the charging time of the stator coils. Each stator coil requires less current than an electromagnetic railgun and has a high energy utilization rate, which is very useful for accelerating large mass objects.
