What happens to maglev trains when they encounter ice?
Maglev means magnetic levitation. So the train is not touching the track, in fact once the engines are fired up, the entire train lifts about one cm off the track. So ice is irrelevant to a maglev vehicle. Unlike conventional vehicles which use friction as a braking force, e.g., tires on a road, a maglev uses eddy currents produced in the track as a result of magnetic force as both propulsion and braking methods.
WHAT KIND OF TRANSIT MASSEGE CAN BE OFFERED IN THE TRAIN?
Take off messages on the train
What is principle of maglev train?
Magnetic levitation is the method used for maglev trains. In order to levitate a train, superconducting magnetic coils are used to completely expel the magnetic fields which will cause the trains to fly off its track.
How does a maglev train move forward?
Magnets attract or repel (opposite poles attract: like poles repel), and electro-magnets can be turned on and off, or have their poles reversed, in an instant. So magnets are used instead of engines in a maglev train.There are two kinds of Maglev systems:EMS - ElectroMagnetic Suspension (Germany and China) - "pull" system. Magnets in the train are pulled forward by magnets in the track which are turned on just before the train arrives, and turned off as soon as the train is on top of them.EDS - ElectroDynamic Suspension (Japan) - "pull, neutral, push" system. Superconducting magnets in the train are pulled forward by track magnets. When the train is over the track magnet the track switches to neutral, then to the opposite polarity. So the magnet behind the train then pushes it forward.by massive magnets !
What are the disadvantages of a MagLev train?
Cost, quite simply. As opposed to traditional trains where power comes from the pushcar of the train, a Maglev train doesnt propel itself, the track does. This means that expensive electromagnets with several electrical substations dotted along its path need to be constructed throughout the entire track's length. The initial cost of building these lines is too high for economically disadvantaged countries. The disadvantages of using the Maglev is that the Maglev tracks cost more than railroad tracks do. Whole new sets of tracks would need to be built for the Maglev to run. Many transportation vehicles in Europe run on existing track, like the TGV trains in France. Although Maglevs are pretty quiet, there is still noise caused by air disturbance. Also another disadvantage is that if a high speed line between two cities it built, then high speed trains can serve both cities but more importantly they can serve other nearby cities by running on normal railways that branch off the high speed line. The high speed trains could go for a fast run on the high speed line, then come off it for the rest of the journey. Maglev trains wouldn't be able to do that, they would be limited to where maglev lines run. It would be very difficult to make construction of maglev lines commercially viable unless there were two very large destinations being connected. Of the 5000km that TGV trains serve in France, only about 1200km is high speed line, meaning 75% of TGV services run on existing track. The fact that a maglev train will not be able to continue beyond its track may harm its usefulness.

What kind of energy do video games use?
Video game consoles run off electricity.
What kind of circuit will not allow electricity to flow because there is a disconnection or the switch is off?
All electricity or electronic circuits will not allow the current to flow if they have switching devices in series in their circuits.
When a moving train stops kinetic energy is changes to what kind of energy?
Heat energy cause it stops and let's off all the heat it just gained from the train tracks.
How much electricity does a microwave give off?
A microwave does not give off electricity.
Is a maglev train faster than an airplane?
A Magnetic Levitation or MagLev train can travel at a higher rate of speed than a normal train because the train does not make contact with solid material. It is suspended above the guideway by magnetic repulsion and only has the friction of air and inertia as a resistance to movement. The speed of the train is regulated by the frequency of the power applied to the magnets of the linear motor composed of the electromagnets on the train and in the guideway.
Does a lamp use electricity when it is turned off?
A standard lamp will not use any electricity when it is off.
