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\na attracting the metallic train to each new section of track with fluctuations in the magnetic field.\nb changing the compatibility and interaction of the magnets in the track and the magnets in the train.\nc inducing a magnetic charge in the train that pulls the train along the track at a high rate of speed.\nd using the magnetized coil running along the track to repel the large magnets on the trains undercarriage.

Answer

Brief Explanations:

Maglev trains use the interaction between magnets on the track and those on the train to achieve lift and propulsion. By changing the magnetic - field interactions (such as repulsion and attraction), the train can move. Option B correctly describes this principle. Option A is incorrect as it's not just about attracting to new track sections with magnetic - field fluctuations. Option C is wrong because it's not about inducing a magnetic charge in the train in that way. Option D only focuses on repulsion and is an incomplete description.

Answer:

B. changing the compatibility and interaction of the magnets in the track and the magnets in the train.
