WHAT IS MAGLEV?

Maglev, or EMS (Electromagnetic Suspension) Is Suspension Via Electromagnetism, or in other words, magnetic levitation. Maglev can be used in trains, Transport, Or many forms of generally playing around. A simple example of EMS is a magnetic spinning top. Because opposites attract, and similar forces repel, if you put two south poles together they repel, so the South Pole of a top facing the South Pole of a plate of metal, the top will levitate, and promptly fall over.

Maglev in trains

In 1984, The First passenger on a maglev train rode at the Birmingham International Airport, at an average speed of 26 mph (42 kph). There are quite a few Maglev trains in the world, some of the most famous being in Shanghai, Germany, and Japan. The Jiatong Institute is developing an EMS train that can reach speeds of up to 1,800 mph (2,900kph). The fastest maglev train as of now is The Shanghai Maglev Train which has a top speed of 268 mph (431 kph).

OTHEr forms of ems

There are other forms and uses for EMS such as Quantum Levitation, which involves freezing a magnet to somewhere below 80°K (-315.67°F or -193.15°C) so that the Electrons form Cooper pairs and all have equal negative energy levels creating no resistance to changes in energy, which allows the substance to mirror the poles of a magnet that it is placed on top of, allowing it to levitate. You would be unable to make a train out of this, as the human body goes into Hypothermia at 308.15°K (95°F or 35°C) A mere 228°K above the Required temperature. Quantum Levitation can Be used for other purposes, As seen in Bioshock Infinite, A video game made by Irrational Games, In which the floating City of Columbus Has a frozen Foundation that runs along Magnetic rails placed all across America. Although we are Quite far from Flying cities, We can still create theoretical Vehicles that run on Quantum Levitation.

Summary

In this presentation, We learned about What maglev is; we learned about its history; And about its other properties and uses.
