Introduction

According to modern quantum theory, electromagnetic radiation is a complex phenomenon characterized by the propagation of energy in the form of discrete packets known as photons or light quanta. These photons traverse through free space or a material medium at the universal speed of light, exhibiting dual properties of waves and particles. As electromagnetic radiation travels, it manifests as electric and magnetic fields oscillating perpendicular to each other, forming electromagnetic waves across a broad spectrum of frequencies. These waves encompass various forms of radiation, including radio waves, visible light, and gamma rays, each distinguished by its unique intensity and frequency profile.

Our project embarks on a journey to harness the intricate dynamics of electromagnetic force in propelling a projectile through a carefully constructed copper coil, thereby creating what we term as an "electromagnetic hyperloop." This ambitious endeavor involves leveraging the principles of electromagnetic waves to energize a spiral copper coil, effectively transforming it into an electromagnetic accelerator. The primary objective is to propel a metallic projectile through the coil, utilizing the generated electromagnetic force to achieve significant acceleration.

By employing this model, we seek to unravel the underlying mechanisms of electromagnetic hyperloop technology, thereby shedding light on its potential applications across diverse fields.

Hypothesis

Our hypothesis posits that the process of charging electricity through a copper coil will instigate the creation of a robust electromagnetic field confined within the coil's confines. This electromagnetic field, a consequence of the interplay between electric currents and magnetic fields, is anticipated to serve as the driving force behind the propulsion of a metallic projectile. As the electromagnetic field exerts its influence, imparting a force upon the projectile, we anticipate witnessing a notable acceleration in its velocity as it traverses the length of the copper coil. This phenomenon, characterized by the rapid and efficient transfer of kinetic energy from the electromagnetic field to the projectile, serves as a tangible manifestation of the overarching concept of electromagnetic hyperloop. Through empirical observation and rigorous analysis, we aim to validate our hypothesis and gain deeper insights into the intricate dynamics of electromagnetic propulsion systems.

This circuit, containing essential components such as capacitors and trigger mechanisms, serves as a vital source of electrical energy for our experiment. By carefully dismantling the camera and extracting its circuitry, we acquire the necessary infrastructure to facilitate the generation and transmission of electrical pulses required to activate the electromagnetic field within the copper coil.
Wrapping the Copper Wire Around the Rail: Having obtained the main circuit from the disposable camera, we meticulously wrap the copper wire around the rail in a spiral configuration. This process is conducted with precision to ensure uniformity and optimal contact between the wire and the rail. The spiral arrangement of the copper wire maximizes its surface area within the electromagnetic coil, enhancing its efficacy in generating and sustaining electromagnetic fields. Through this step, we establish the foundation for harnessing electromagnetic forces to propel our projectile along the designated path.

This action initiates the discharge of electrical energy stored within the capacitor, leading to the generation of electromagnetic fields within the copper coil. As the circuit completes its charging cycle, electromagnetic forces accumulate within the coil, poised to propel the metallic projectile upon activation.
