Context: China unveiled a new high-speed Maglev train that can cover 1,200 km (Beijing–Shanghai) in just 2.5 hours, outperforming even airplanes.
About High-Speed Maglev Train:
• What is a Maglev Train? Maglev (Magnetic Levitation) train is a wheel-less rail vehicle that levitates using magnetic force, eliminating friction and enabling high-speed, smooth transport.

• Concept and Development:
• Inventors: Conceptualized by Robert Goddard and Emile Bachelet in the early 1900s. First Use: Commercially launched in 1984 in the UK and now operating in China, Japan, and South Korea.

• How Maglev Works?
• Magnetic Suspension: Opposing magnetic forces lift the train off the track (no wheel contact). Propulsion via Magnetic Coils: Alternating electric current in the guideway changes magnetic polarity to push or pull the train. Two Systems: EMS (Electromagnetic Suspension): Uses magnetic attraction. EDS (Electrodynamic Suspension): Uses magnetic repulsion with superconductors.
