This document discusses magnetic levitation trains, also known as maglev trains. It describes two main systems used in maglev trains - electromagnetic suspension (EMS) and electrodynamic suspension (EDS). EMS uses electromagnets to levitate the train above the track, while EDS uses both electromagnets and the interaction between magnets and conductive materials to lift and propel the train. Diagrams are included showing how EDS maglev systems work and how EDS trains move.
