PROBLEM TO BE SOLVED: To provide a roadbed-installed superconducting magnetically levitated system that concurrently functions as a propulsive levitation guide, wherein a null flux cable is unnecessary, upper and lower magnetic springs are soft and thus coil installation accuracy is not strict, and further a superconducting coil can be readily installed on a vehicle. SOLUTION: The superconducting magnetically levitated system includes a ground coil 2, having coil 2A groups in a shape of figure "8" installed on a roadbed, a distribution line 3 connected to the ground coil 2, and a substation 1 on the ground having a three-phase alternating-current power supply connected to the distribution line 3.
