  At the Yamanashi maglev test line, two types of ground coils are used. One is for propulsion and the other for levitation and guidance. To confirm the characteristics of electromagnetic force of the ground coil for levitation and guidance, we measured the electromagnetic force directly with a measurement coil. The measurements of electromagnetic force, magnetic spring and current were in good agreement with the computed values to prove that the characteristics of electromagnetic force satisfy the design requirements.
