![]() ![]() Both loops use magnetic repulsion to keep the train car in the optimal spot the further it gets from the center of the guideway or the closer to the bottom, the more magnetic resistance pushes it back on track. Three types of loops are set into the guideway at specific intervals to do three important tasks: one creates a field that makes the train hover about 5 inches above the guideway a second keeps the train stable horizontally. Like ordinary magnets, these magnets repel one another when matching poles face each other. In Maglev, superconducting magnets suspend a train car above a U-shaped concrete guideway. In the United States, a number of routes are being explored to connect cities such as Baltimore and Washington, D.C. The first commercially operated high-speed superconducting Maglev train opened in Shanghai in 2004, while others are in operation in Japan and South Korea. Superconducting magnets are electromagnets that are cooled to extreme temperatures during use, which dramatically increases the power of the magnetic field. He dreamed up the idea of using superconducting magnets to levitate a train car. The idea came to Powell as he sat in a traffic jam, thinking that there must be a better way to travel on land than cars or traditional trains. James Powell and Gordon Danby of Brookhaven received the first patent for a magnetically levitated train design in the late 1960s. Maglev - short for magnetic levitation - trains can trace their roots to technology pioneered at Brookhaven National Laboratory. What if you could travel from New York to Los Angeles in just under seven hours without boarding a plane? It could be possible on a Maglev train.
