The Maglev Train (Part 2)

Hello everyone,

As many of you are aware, I am conducting research on the Maglev Train for my 20% Time in Physics. On my previous post, I explained that "Maglev" stands for Magnetic Levitation.

During my period of research, I learned that the Maglev Train basically uses the basic principles of magnets or more specifically, Electromagnetic Suspension (EMS).

By now, you should know all about electromagnets and that opposite poles attract and similar poles repel. That is the basic principle behind electromagnetic propulsion. Electromagnets attract metals just as normal magnets would, but the magnetic pull in electromagnets are only temporary.

The Maglev Train works by orientating the magnets on top of the guide way to repel similar poles in the bottom of the train. This is why the train levitates. The Maglev train contains a system of groups of extremely powerful superconducting electromagnets. These magnets use less electricity than the normal electromagnets, but they have to be cooled to very low temepratures rounding from -269 degrees Celsius to -196 degrees Celsius.

The difference between a Maglev train and a conventional train is that Maglev train does not use a similar engine. The engine for a Maglev train does not use fossil fuels, instead the train uses the magnetic field created by the electrified coils that are built in the guide way walls and track to propel itself.

I have yet to confirm whether i would be able to make a live showcase of a Maglev Train during the presentation. My apologies.
