The infographic that shows the operation of the Maglev train (an acronym for Magnetic Levitation Tranport) was selected by Editora do Brasil to appear in its 9th year Tempo de Ciências (Science Time) school manual, with some minor modifications, derived from the publisher's pedagogical plan. The Maglev train works by means of a magnetic levitation system, produced by magnets that support and propel the train; this system prevents rubbing and friction. Thanks to this, the train can reach speeds of over 500 km/h. It is also a quieter and smoother means of transport than conventional trains in railroads. The Chinese city of Shanghai was the first to have a commercially operational Maglev train, which travels the 30 km that separate the city from the airport in 7 minutes.
