A:
In the future, maglev trains might be an option as a mode of
transportation. In the structure of the track, there is a magnetized
coil, called a guideway, that runs along the track and repels the large
magnets on the trains undercarriage. This repelling force raises the
train to about .39 to 3.93 inches above the guideway. When the train is
raised, magnetic fields are created by the power supplied to the coils
within the guideway walls; these magnetic fields pull and push the
train along the guideway. The electric current is changing in polarity
because they are continuously alternating in the coils, and this change
in polarity causes the magnetic field in front of the train to pull the
train at amazing speeds. Also, the magnetic levitation train can travel
without friction because it rests above the guideway, with a layer of
air in between, to achieve speeds at 310 miles per hour.
