This baccalaureate thesis investigates the energetic benefits of using permanent magnets in model trains. Its aim is to analyze how magnets can reduce energy consumption and increase efficiency. To this end, the physical principles of permanent magnets are explained, and three concepts for implementing them in model trains are evaluated. A railcar and a track with integrated time-measurement capabilities are then constructed. The model is suitable for use in physics classes and enables precise timing measurements. The analysis of travel times in the context of the physics of an inclined plane shows that using permanent magnets can achieve energy savings of over 23%. The project also discusses whether the setup is suitable as a measurement system for determining magnetic force. Overall, this work provides valuable insights into the use of permanent magnets in model trains and their potential to optimize real transportation systems.
