Applications: Maglev Trains
There are two basic designs of magnetically levitated (maglev) train. Click on the buttons above to investigate the workings of the two desgins.
Levitation Systems
In electrodynamic suspension (EDS) systems, superconducting magnets are used to create repulsive forces which lift the train off the rails. This means that the field does not have to be adjusted due to the more stable nature of the repulsion. However, it does mean that there are significant fields within the train carriages and that the train has to be wheeled at low speeds.

Suspension Systems
In electromagnetic suspension (EMS) systems, superconducting magnets are used to create an attractive force which lifts the train up. This requires constant measurement and alteration of the field strength to keep the separation between the magnets constant. However, this system has negligable fields within the train and requires no secondary propulsion system.
