the materials used
Maglev trains have the technology to reach speeds in excess of 3,000 mph but any speed in excess of 300-400mph becomes impractical. The top speed depends more on how and where the maglev is built, how far apart stations are, and how much maintenance cost is considered acceptable. So, for the trains proposed so far today and may be in service in the next 20 years, it maglev trains will not exceed 400mph.
maglev is short for Magnetic Levitation.
"Maglev" is.
You must mean a Maglev train. A Maglev train operates on maglev (magnetic levitation). It uses electromagnets (and possibly superconductors) that repel each other to lift the train above the ground to reduce as much friction as possible.
Not in the immediate future, it isn't. The cost of the track would be prohibitive.
They get on from an opening passage way that comes out of the maglev train
It's all to do with magnetic repulsion - when the train is moving, the two magnets have the same pole, and so repel each other, creating a "cushion". It's a bit like the principle of two bar magnets in school, matching north pole to north pole.
Magnetism elevates the maglev train because like forces repel. Maglev trains are not suspended, but are elevated.
Yes, maglev trains can be built underground. In fact, the majority of the Chuo Shinkansen maglev line being built in Japan will be underground.
Earnshaw from Cambridge University , he is the first man who posted the principle of maglev. But Hermann Kemper, a German engineer, is the first man who is proposed as the farther of maglev.
The maglev train floats over its track using an electromagnet. Maglev trains have managed speeds in excess of 370mph. A model of the maglev train uses two permanent magnets to get the model to float over the track.Describe how the magnets must be arranged to get the model Maglev Train to float.
