Maglev (magnetic levitation) is a transport that uses the magnetic levitation to reach maximum speeds of 590 km/h. The magnetic levitation for the ground transportation is one of the most innovative technologic feats for the passengers transportation.
But first, what is magnetism? Magnetism is defined as the attraction force of magnets that have a positive pole and a negative pole, known as a dipole.
This way, thanks to the propulsion created based on the science of magnetism, the friction of the rails is eliminated, increasing speed, safety and decreasing carbon emission. Maglev has become the technological innovation of public transport of the future.
The disadvantage is the high cost of the lines, which has limited commercial use. This high cost is derived from several important factors: the first and main is the high cost of the infrastructure necessary for the track and the electrical system, and another no less relevant is the high energy consumption.
Other tours are under study, mainly in China and Japan. In Germany, the construction of maglev lines for passengers has been discarded for the time being because of the onerous construction and maintenance costs.
The maximum demonstrated speed of a real maglev in commercial operation is that obtained by the German train Transrapid installed in Shanghai, China, which transports passengers along 30 km in just seven minutes and twenty minutes.
