This project presents the design of an electromagnetic launcher, a device that demonstrates how electricity and magnetism can be used to produce motion. Instead of relying on chemical reactions, the system uses electrical energy supplied by a battery to energize a copper coil. When electric current flows through the coil, a magnetic field is generated, which propels a small metal object forward along the launcher’s barrel.The operation of this device is based on Ampère's Law, which states that an electric current flowing through a conductor produces a magnetic field around it. In this project, the copper coil acts as the conductor, and when it is energized by the battery, it creates a magnetic field that accelerates the metal object. This demonstrates the relationship between electricity and magnetism and how electrical energy can be converted into kinetic energy.This project demonstrates fundamental principles of electromagnetism in a practical and understandable way. It helps students visualize how electric current generates magnetic fields and how these magnetic fields can be used to produce motion. The concept is related to many modern technologies such as electric motors, magnetic transportation systems, and electromagnetic launch technologies used in engineering and scientific research.Overall, the electromagnetic launcher serves as an educational model that highlights real-world applications of electromagnetic principles and encourages a deeper understanding of physics concepts related to electricity, magnetism, and energy conversion.
