Earnshaw’s theorem states that a collection of point charges cannot be maintained in a stable Earnshaw’s theorem forbids magnetic levitation in many common situations. If the materials are not hard, Braunbeck’s extension shows that. The electromagnets on the underside of the train pull it up to the ferromagnetic stators on the track and levitate the train. The magnets on the side keep the train . Safety of High Speed Magnetic Levitation Transportation Systems: German Published Date: Language: English. Filetype [PDF MB].

Earnshaw’s theorem – Wikipedia

This report is the second lefitation a series of reports addressing the safety of high-speed maglev trains and presents the results of the review to determine the suitability ofGerman safety requirements for application to maglev systems as proposed for U. The intent of the review was to compare the German filetyle U. The German safety requirements were reviewed in terms of safety related functional areas of the following areas of the following seven maglev system elements: Potential safety concerns for each of the maglev system functional areas were identified.

The German safety requirements and the applicable U.

Recommendations are also included for FRA consideration. In general, the German effort appears to ensure the same high level of safety for maglev trains that is expected in the United States for similar ground transportation technologies.
