Atracktion How do Maglev trains use magnet it to function? Nguyen, Mindy Physical Science, Period 4 Abstract- Maglev trains, also known as magnetic levitation trains, are public transportation vehicles that are commonly used in Spain, China, and other parts around the world. They are mainly known for using magnetism in order to "levitate" above the tracks. Maglev trains are also known to be remotely quieter than normal trains and emit lower amounts of carbon dioxide. Purpose- I wanted to find out how Maglev trains were able to use magnets in order to move around subways. The reason I chose this topic is that magnets are seen and used everywhere, whether it's for entertainment purposes or for technical and/or scientific reasons. The Maglev…show more content…
The main reason that they differentiate is not only the gap in speed rates, but due to the excessive use of magnets that super-conducts and helps it "levitate" During the process of building a Maglev train cart, electromagnets are used. They are made when electric currents flow to coils of metal that's aligned to the track. This is also stated in Faraday's Law of Induction. These electric currents then repel the large magnets that are stored under the train's framework, which is also known as the undercarriage. This process is quite similar to when the North and North poles repel and when the South and South poles…show more content…
This then causes the train to be able to glide super-fast and travel up to 268mph. The Maglev train is able to move quickly due to the lack of friction that would normally slow down a normal train. Instead, the Maglev train rests on a mat of air, having little to no friction. Once the train starts gliding, electricity is not needed for the train to keep moving. Instead as a replacement for fuel, three large magnets are lined up in the bottom of the train, and two magnets in the front and back. The magnet in the front attracts while the magnet in the back repels, which pushes the magnets in the middle to move forward in unexplainable speeds. To keep it moving, the magnets in the guideway push and pull the train. Since the magnets in the guideway are charged up by controlled currents that constantly alternate, they can easily change their push and pull poles quickly to push the train forward, and thus how a Maglev train is created and used. Reflection- The most thing I've learned from this research topic is how the magnets repel and attract in order for the train to start moving, which is what I've discovered, a much more eco-friendlier way for vehicles move. I do not have any further investigations as a result of my research, but I would like to learn more ways of how magnets are used in our everyday lives. The most difficult part to accomplish was how to be elaborate
