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:

1. 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.
2. 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.

Well it has to do with making the charge exerted from the rails positive or negative. If you manipulate this, otherwise known as the polarity, you can create what is called magnetic friction. When two very powerful magnets create magnetic friction, the stopping power is enormous. It's a very good break design

Maglev is the shortened form of Magnetic Levitation. It uses a series strong magnets to raise a train above the rails and propel it forward by magnetic conduction. There are several maglev trains in operation in the world.

Why is the maglev train called the maglev train?

maglev is short for Magnetic Levitation.

What does the magnetism do in maglev trains?

Maglev is a contraction of Magnetic Levitation. Magnets of the same polarity are used to levitate the train so that there is no friction between train and rail. Electromagnets of opposing polarity are switched on in sequence ahead of the train to pull it forward.

What is the type of current in the maglev train ac or dc?

maglev train works on alternating current..The electric current supplied to the coils in the guideway walls is constantly alternating to change the polarity of the magnetized coils. This change in polarity causes the magnetic field in front of the train to pull the vehicle forward, while the magnetic field behind the train adds more forward thrust.

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.

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.

Why does a maglev train need to float over the track while moving forward?

i dont know. am searching for the same ans.

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.

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.

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.
