Magnetic Levitation in Motion

Abstract

This project analyzed the physics of magnetic propulsion by modeling the propulsion system of a MagLev train. A scale model was created using electromagnets to simulate the attracting/repelling forces that cause MagLev trains to move. The speed of the model train was recorded as a function of the pull force of the electromagnets. A magnet strength equivalent to 11 pounds of pull force was shown to produce the most cost-effective results. Next, the levitation system of a MagLev train was studied by creating a scale model of a track using neodymium magnets. The levitation height was measured as a function of the pull force of the magnets. No strong increase in height was observed. Thousands of people use MagLevs daily in Japan. In Japan, MagLevs shorten travel times for commuters significantly, in addition to decreasing traffic congestion and pollution on busy freeways. Many countries, including the US, are planning to build MagLev trains to reduce travel times in their countries. The same principles tested here can be scaled up and applied to real MagLev trains in order to make travel faster and more cost effective for the average citizen.
