Electromagnetic Cannon

Electromagnetism

★Exhibit Content: Principle of electromagnetic launch, application of electromagnetic force ★Interaction: Electromechanical interactive experience ★Operation: Operate the electromagnetic cannon device, launch the iron ball, observe the acceleration process of the iron ball in the track and the effect of hitting the target, and intuitively experience the effect of electromagnetic force. ★Exhibit Description: The exhibit consists of an electromagnetic cannon launcher, barrel coils, iron ball, recovery trough, control system, etc. Participants operate the electromagnetic cannon device; the control system collects sensor signals at the entrance of each stage of coils and supplies pulse current to the corresponding coils, generating a strong pulsed magnetic field in the coils, attracting the ferromagnetic projectile to move forward; each time it passes through a stage of coils, the steel ball is accelerated once, ultimately reaching the kinetic energy required to strike the target. It intuitively demonstrates the working principle and application scenarios of electromagnetic launch technology, transforming abstract electromagnetic principles into operable fun interactions, suitable for science and technology museums, national defense science popularization museums, and primary and secondary school science education scenarios. ★Scientific Principle: This exhibit is based on the principle of electromagnetic launch: The electromagnetic cannon is an advanced kinetic energy device made using electromagnetic launch technology. Through the pulsed magnetic field generated by multiple stages of coils in the barrel, it accelerates the ferromagnetic projectile stage by stage, converting electromagnetic energy into the kinetic energy of the projectile; Compared with traditional gunpowder-propelled devices, the electromagnetic cannon can greatly increase the speed and range of the projectile, and can be applied in fields such as space-based anti-missile systems, air defense systems, anti-armor weapons, and naval ship equipment; By simulating the launch process, the exhibit intuitively reveals the mechanism of electromagnetic force and the process of energy conversion, allowing visitors to understand the scientific principles and application value of electromagnetic launch technology.
