Two plastic angle pieces are placed parallel to each other on a cardboard sheet with a 40 millimeter gap between them. Two magnetic strips are also placed in parallel between the plastic pieces and should have a gap of 10 millimeters.

The train has two magnets on the bottom of it. These magnets push against two magnets that form the tracks. If the force from the magnets is strong enough, the train will float in the air above the tracks.

Create a Graph. Retrieved June 25, Note: A computerized matching algorithm suggests the above articles. Disconnect the battery and replace it with a small resistor. Now turn the axle. There should be a measurable voltage across the resistor. The same device that converts electrical energy to mechanical energy can work in reverse to convert mechanical energy to electrical. Assembly instructions for your maglev train. Peel the paper backing off the two short magnetic strips and attach them to one side of the wooden block, as shown in Figure 2.
The edges of the strips should line up with the edge of the block. When it's complete, the train will slash the nearly three hour trip to just 67 minutes [source: Reuters ]. China is seriously considering dozens of potential maglev routes, all of them in congested areas that require high-capacity mass transportation. These won't be high-speed trains. Instead, they'll move lots of people over shorter distances at lower speeds.
Nevertheless, China manufactures all of its own maglev technologies and is about to unveil a third-generation commercial maglev line with a top speed of around mph kph and — unlike previous versions — is completely driverless, relying instead on computer sensors for acceleration and braking The country already has some maglev trains in operation but they need a driver. It's impossible to know exactly how maglevs will figure into the future of human transportation.
Advances in self-driving cars and air travel may complicate the deployment of maglev lines. If the hyperloop industry manages to generate momentum, it could disrupt all sorts of transportation systems. And some engineers suspect that even flying cars, though incredibly pricey, might trump rail systems in the future because they don't need massive infrastructure projects to get off the ground.
Perhaps in just a decade or two, nations around the world will have come to a verdict on maglev trains. Maybe they'll become a linchpin of high-speed travel, or simply pet projects that serve just fragments of certain populations in crowded urban area. Or perhaps they'll simply fade into history, a nearly magical form of levitation technology that just never really took off. Sign up for our Newsletter!

A magnetically levitated maglev train developed by Central Japan Railways Co. A large electrical power source Metal coils lining a guideway or track Large guidance magnets attached to the underside of the train.
The Maglev Track " ". The Maglev track allows the train to float above the track through the use of repelling magnets. Learn about the Maglev track and see a diagram of a Magelev track. Maglev Accidents. Electrodynamic Suspension EDS " ". Above is an image of the guideway for the Yamanashi maglev test line in Japan. Photos courtesy Railway Technical Research Institute. Maglev Technology In Use " ". Sources Beanland, Christopher. May 29, June 15, Department of Energy.
The vehicle comes safely to a stop rather than suddenly falling onto the track. Even if one substation suffers an outage, electricity can be fed from an adjacent substation, providing a high degree of redundancy. Even if one substation suffers an outage, electricity can be fed from an adjacent substation to keep the train in operation.
The Superconducting Maglev is a quake-resilient system. Its vehicle operates without contact, levitating about 3. Magnetic force from levitation and guidance coils keeps the vehicle centered in the guideway, both vertically and horizontally, preventing derailment at the time of an earthquake.
The Chuo Shinkansen will have most of its terminal stations Tokyo, Nagoya and Osaka as well as most of its routes in tunnels and underground structures.
