Magnets can be used to solve many engineering design issues. The Maglev Train built in England in 1984 to transport people
between Birmingham Airport and Birmingham International Railway station uses magnets as an alternative energy source. With
maglev, the train travels along the track using magnets to create both lift and propulsion by
es )
A)
attracting the metallic train to each new section of track with fluctuations
in the magnetic field.
B)
changing the compatibility and interaction of the magnets in the track and
the magnets in the train.
inducing a magnetic charge in the train that pulls the train along the track
at a high rate of speed.
D)
using the magnetized coil running along the track to repel the large
magnets on the train's undercarriage.
