If you have an automobile, you may be aware of the cost of gasoline. If not, you have seen automobile owners purchase gasoline. If you drive down the highway, the automobile uses gasoline. The car engine uses gasoline for a source of energy to make the car move. The engine makes the wheels move.
As the wheels move they produce rolling friction. The engine must overcome this rolling friction. The weight of the engine and transmission on the wheels adds to this rolling friction. If a way could be found to remove the engine and transmission from the car, the rolling friction could be greatly reduced. Maybe instead of having the engine as part of the car, we can place it between two tracks. We will make it magnetic. We will try that.
While we are at it, maybe we can reduce the rolling friction all together. Maybe we can use the repulsive force of magnets to hold our vehicle a millimeter or two above a track. That would do away completely with rolling friction. Yes, We will have the motor a long strung out electric motor between the tracks and we will not need wheels to drive the vehicle. Then we can levitate the vehicle a few millimeters above the track. What do you say we call it a maglev train. Once we get out the kinks, it will be a lot less expensive to run than current equipment.
Such trains will not be built any time soon in the United States except for short distances. Current train tracks simply are not straight enough. The distance between standard gage tracks can vary in width by 1/2 inch. That is far too much for a maglev train. It would be necessary to secure new right of way.

∙ 14y agoThey are three times faster than the average car and dont release as much carbon dioxide as normal trains. plus, because they use electromagnets they need less maintenence.

Why is the maglev train called the maglev train?
maglev is short for Magnetic Levitation.
When were maglev trains first being used?
MagLev trains were first designed by a German man named Hermann Kemper. he was the first man to design and patent a MagLev train. The first MagLev train to be built and used was designed by Thyssen Henschel, another German, in the 1970's. The first passenger-carrying MagLev train was introduced in 1979 at the International Transportation Exposition in Hamburg, Germany. Thus began the MagLev train.
What is the force that lifts up and moves maglev trains?
It cannot. The magnets used for a maglev train must be engineered and built at very tight tolerances to allow a maglev train to function. Each magnet is specifically built for the maglev train, they cannot be "strengthened" versions of a magnet not made specifically for the train.
What is the name of the german-made maglev train?
The Transrapid.
If someone wanted to ride on a maglev train what city could they go to?
The Chinese city of Shanghai is reported to have a Maglev train in commercial use. The Japanese and Germans are working on Maglevs so are the USA.
Why is the maglev train called the maglev train?
maglev is short for Magnetic Levitation.
What type of train uses magnets?
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.
How does magnetism keep the cars suspended on a maglev train?
Magnetism elevates the maglev train because like forces repel. Maglev trains are not suspended, but are elevated.
Does Italy have Maglev train?
no
What controls the levitation of the cars of a Maglev train?
The levitation of a maglev train is controlled by safety critical microprocessors (computers).
How does balance effect the maglev train?
It doesn't. The maglev train is engineered for weight distribution that is unaffected by normal loading.
What is electromagnet train?
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.
How do you people get on maglev trains?
They get on from an opening passage way that comes out of the maglev train
What is the weight of the maglev train?
== ==
What are the parts of a maglev train?
barney is on the train chewing chicken
Who is the inventor of the maglev train?
The maglev train was first invented in 1902 . It was invented by a guy named Alfred Zehan.
How does the maglev train differ from a normal train?
The biggest difference is that a maglev train is not touching anything while it is traveling, while a normal train is sitting on steel rails at all times.
