My project "Destination Vacation" is about Maglev trains and how they are run some topics I focus on are 1. How it runs 2. EDS and EMS and third the difference bewtween different countries and there futuristic trains. The Main topic of my project is the difference bewtween EDS and EMS Maglev systems.
EDS and EMS
EMS or electro magnetic suspension is one of two types of Maglev systems. EMS uses attractive forces to levitate the train. On the train to the left bottom of it are levitation magnets in the middle is a guideway and on the right are guidance magnets. The levitation magnets will be attracted to the conductors placed on the bottom side of the guideway. The attractive force bewtween them will overcome the gravitational force and the train will levitate. The guiding magnets on the other side guides the train so it wont hit the wall and creat friction hence the name frictionless train.
The EDS system used by Japanese engineers, it focuses on repelling magnets and using magnets with the same polority to create repulsive friction which is the friction bewtween repelling objects. The repulsive friction will happen bewtween the levitation magnets on the left and right of the train and the guideway on the bottom of it. eventually the repulsive force from the moving train will be enough to overcome the gravitational force and the train will levitate.
Different countries- Different Trains
The Japanese engineers tuse an electrodynamic suspension (EDS) system, which is based on the repelling force of magnets. The key difference between Japanese and German maglev trains is that the Japanese trains use super-cooled, conducting electromagnets. This kind of electromagnet can conduct electricity even after the power supply has been shut off. so incase of emergency passengers will still feel safe In the EMS system. The Germans use and inductrack system which is a newer type of EDS that uses room tempeture magnets to produce magnetic fields and have the train run that way instead of electromagnets or super cooled magnets.
Here are some facts about maglev trains and systems.
1. Maglev trains are as fast as aeroplanes. 2. Most trains go one rail. 3. Maglev comes from MAGnetic LEVitation.4.It floats/levitates. 5. They make no sound because they are frictionless. 6. The stronger the magnet the faster the train. 7.there are coils on the walls that are used as conductors for the electricity one the train.
