Paragraph: Modern trains are based on Maglev technology in which trains are magnetically leviated, which runs its EDS Maglev system. There are coils on both sides of wheels. Due to motion of train, current induces in the coil of track which levitate it. This is in accordance with Lenz's law. If trains lower down then due to Lenz's law a repulsive force increases due to which train gets uplifted and if it goes much hi

Options

  1. ATrain experiences upward force according to Lenz's law

  3. CRetardation
  4. DBy Lenz's law train experience a drag

Correct answer

D. By Lenz's law train experience a drag
