Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the core technology?Magnetic Levitation (Maglev) employing either Electromagnetic Suspension (EMS) or Electrodynamic Suspension (EDS)
2. What is the propulsion mechanism?Linear motor technology integrated into the guideway and vehicle
3. What are AMMDes and how do they move?AMMDes are advanced magnetic-levitation trains that use powerful magnets to lift and push the train along a special guideway, so they can travel very fast without wheels.
4. How do AMMDes float above the tracks?They float because magnets on the train either pull up on metal rails (EMS) or push away from metal coils (EDS), creating a gap that keeps the train suspended above the track.

Electromagnetic Suspension (EMS): A maglev system using attractive magnetic forces between electromagnets on the train and the guideway.
Electrodynamic Suspension (EDS): A maglev system using repulsive magnetic forces generated by superconducting magnets on the train.
Linear Motor: An electric motor that produces linear motion rather than rotational motion, used for propulsion.
Guideway: The specialized track or pathway designed to support and guide a maglev train.
