A line of strong magnets is arranged so their fields interact with a conductive surface, creating lift without physical contact. When magnetic forces oppose gravity, friction drops almost to zero, allowing trains to glide smoothly instead of rolling on wheels. This same principle is used in maglev trains that can exceed 600 km/h while remaining stable and quiet. Because there
