How do maglev trains work using electromagnets?
In Maglev, superconducting magnets suspend a train car above a U-shaped concrete guideway. Like ordinary magnets, these magnets repel one another when matching poles face each other. Here, both magnetic attraction and repulsion are used to move the train car along the guideway.
How do trains use electromagnetic induction?
The electromagnet at the undercarriage beneath the train is oriented towards the guidance rail, creating a magnetic force which levitates the train to about 1 cm above the guidance rail; so that even when the train is at rest, it is still levitated. Other guidance magnets ensure the stability in motion.
What is a Maglev train and how does it work?
Maglev (from magnetic levitation) is a system of train transportation that uses two sets of magnets: one set to repel and push the train up off the track, and another set to move the elevated train ahead, taking advantage of the lack of friction.
Do Maglev trains have electromagnetic engines?
In the 21st century there are a few countries using powerful electromagnets to develop high-speed trains, called maglev trains. These trains float over guideways using the basic principles of magnets to replace the old steel wheel and track trains.
Are maglev trains being used today?
Six commercial maglev systems are currently in operation around the world. One is located in Japan, two in South Korea, and three in China. In Aichi, Japan, near Nagoya, a system built for the 2005 World’s Fair, the Linimo, is still in operation.
How does the magnetic field of a maglev train work?
It adjusts the power of the magnetic field produced by electromagnets that levitate an object into the air. As shown in figure 2, there is a guidance magnet on the side of the track that generates the magnetic force that prevents the train from moving side to side. It also designed as the C-form to keep the train in the bounce.
How does a magnetic levitation train be propelled?
It is also possible to switch the rotor and the stato r. In this case the track changes poles and the solenoid on the train can be replaced by a permanent magnet. There are the two basic principles of a linear motor and hence the propulsion of the maglev trains. The forces in a li near m otor are either electro-dynamic or electromagnetic [6].
When did the first maglev train come out?
The first commercially operated high-speed superconducting Maglev train opened in Shanghai in 2004, while others are in operation in Japan and South Korea.
