The invention discloses a suspension-wire-method-based magnetic shaft measuring system of a solenoid coil. The system comprises a metal suspension wire passing through a to-be-measured solenoid coil;and the two ends of the metal suspension wire are connected with a traction weight after going around a positioning pulley. The metal suspension wire passes through a horizontal photoelectric detectormiddle part and a vertical photoelectric detector middle part that are installed by being perpendicular to each other. The metal suspension wire passes through two Helmholtz coil middle parts that are installed by being perpendicular to each other respectively. Light-emitting ends of the photoelectric detectors are connected with driving lines; and receiving ends of the photoelectric detectors are connected with signal detection lines. The metal suspension wire and the to-be-measured solenoid coil are connected with driving power sources respectively. The driving lines of the light-emitting ends of the photoelectric d
