What is the motion of the train on a moving track?
A train travels over a FIXED track not a MOVING track.
If you are riding on a train that speeds past another train moving in the same direction on an adjacent track it appears that the other train is moving backward. why?
because your going forward at a faster speed its hard to explain
What does a MAG-LEV train need to work?
Two opposing magnets (North in the track and South in the train or vice versa), and a heck of a lot of electricity! * Added - To expand on the over simplification above - powerful electro-magnets are placed in the maglev guideway and in the maglev vehicles. A sophisticated computer control system pulses the magnets to provide both upward lift, forward propulsion, and braking. This lets the maglev move and stop in a straight line - for an actual train, there are many more subsystems and components for the train to actually work.
How are magnet's used?
High speed rail systems use MAGnetic LEVitation to reduce friction on the track(s). Hence the term MAGLEV.
What type of friction is involved in train moving along a track?
Rolling Friction
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.
Can you float a person with magnetic force?
Yes, they have already built trains which are held above the track by magnetic fields, they are called Maglev trains(magnet levitation).
How do you align magnets in a maglev model?
I never tried it, but the magnets on the maglev should face opposite to the magnets on the track. If u face north downwards in the maglev, then u'll have to face the north upwards in the track.
What are the structure of a maglev train?
Magnetic levitation trainer do not run on rails but float above them. A current passes through The electromagnets in The track & on The train. The magnetism produced lifts The train upwards.
How are maglev cars suspended?
the track has negative and positive and that's how
Where is the friction on maglev train?
If you have two magnets they each have a north and south pole. The opposite poles will attract and the same poles will repel. Maglev trains create magnet fields on the track bed and the train of the same polarity. By controlling the generating of the fields you can hold up the train and propel it forward. Since the train is not actually touching a track there is no appreciable friction except that caused by the surrounding air. In a vacuum you would have no friction.
Are there maglev trains that use repulsion to move?
Yes, the Japanese system uses magnets that attract, then repell the train.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.
How does a maglev run?
A Maglev (magnetic Levitation) runs in a new technology. Maglev work by magnets. There are large rotating magnets built onto the sides of the track and train. This causes the Maglevs to levitate. This is possible by electromagnetic suspension.
Where is the electromagnet in a maglev train?
the electromagnet is in the track then there are permanent magnets on the very bottom of the train on the part that wraps around the track
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.
Why maglev train is faster than ordinary train?
Because there's no friction between the train and the track. In an 'ordinary' train, friction between the wheels and the rails takes a lot of energy to overcome before the train starts moving. In a Maglev train, the train itself actually 'floats' above the track on a 'cushion' of magnetic foirce. With no friction to slow it down, the train is capable of much higher speeds.
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 !
