I'm not too sure about the advanced physics of this, but I know that it is desired for Maglev trains to not touch the track so that their speed can be maximised, and so there is no wear and tear of the track and contact.
The speed would be maximised because if you don't touch the track there is no friction. Even wheels are slowed by friction so the only way to completely eliminate it is to have no friction.
What else can I help you with?
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).
Is there a limit to maglev trains speed?
There is no inherent limit to the speed of maglev trains, but practical considerations such as track infrastructure, energy consumption, and safety can influence their maximum operating speeds. Currently, the fastest maglev trains have reached speeds around 375 mph (603 km/h) in commercial service.
How do magnetic trains work and what makes them different from traditional trains?
Magnetic trains, also known as maglev trains, use powerful magnets to levitate and propel the train along the track. This technology eliminates the need for wheels and tracks, allowing the train to move smoothly and quietly at high speeds. Unlike traditional trains that rely on friction between wheels and tracks, maglev trains float above the track, reducing wear and tear, and enabling faster speeds and more efficient travel.
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.
What kind of fuel does a maglev train use?
Maglev trains are powered by electricity. They use electric power to propell themselves by creating a magnetic field between the track and the train, allowing it to levitate and move forward without direct contact with the track.
How does magnetism keep the cars suspended on a maglev train?
Maglev trains use powerful magnets to create a magnetic field that repels the train from the tracks, allowing for levitation and propulsion. The system keeps the train hovering at a specific distance from the track, reducing friction and allowing for high-speed travel.
How does friction impact the speed of a magel train?
Friction between the magnetic levitation system and the track can slow down a maglev train by producing resistance. Minimizing friction is key to maintaining the high speeds that maglev trains are capable of achieving. Through advancements in technology and design, engineers aim to reduce friction to optimize the speed and efficiency of maglev trains.
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.
How do maglev trains manage to run without touching the ground?
Maglev trains use powerful magnets to create a magnetic field that lifts and propels the train above the track. This technology allows the train to levitate and move without touching the ground, reducing friction and increasing speed and efficiency.
What are the different types of maglev trains?
The three types of maglev trains are EDS (electrodynamic suspension), EMS (electromagnetic suspension) and stabilized permanent magnet suspension (SPM). * For EMS, same pole electromagnets in the train repel it away from a magnetically conductive track. * The EDS uses electromagnets on both the track and the train, to push the train away from the track. * SPM uses opposite arrays of permanent magnets to magnetically levitate the train above the track. http://trains.suite101.com/article.cfm/maglev_trains
What are the disadvantages of a MagLev train?
Cost, quite simply. As opposed to traditional trains where power comes from the pushcar of the train, a Maglev train doesnt propel itself, the track does. This means that expensive electromagnets with several electrical substations dotted along its path need to be constructed throughout the entire track's length. The initial cost of building these lines is too high for economically disadvantaged countries. The disadvantages of using the Maglev is that the Maglev tracks cost more than railroad tracks do. Whole new sets of tracks would need to be built for the Maglev to run. Many transportation vehicles in Europe run on existing track, like the TGV trains in France. Although Maglevs are pretty quiet, there is still noise caused by air disturbance. Also another disadvantage is that if a high speed line between two cities it built, then high speed trains can serve both cities but more importantly they can serve other nearby cities by running on normal railways that branch off the high speed line. The high speed trains could go for a fast run on the high speed line, then come off it for the rest of the journey. Maglev trains wouldn't be able to do that, they would be limited to where maglev lines run. It would be very difficult to make construction of maglev lines commercially viable unless there were two very large destinations being connected. Of the 5000km that TGV trains serve in France, only about 1200km is high speed line, meaning 75% of TGV services run on existing track. The fact that a maglev train will not be able to continue beyond its track may harm its usefulness.
What train runs without wheels?
Maglev (magnetic levitation) trains run by way of a magnetic field generated by magnets embedded in the track. As such, they have little or no need for wheels.
