The invention discloses a five-leg magnetic stress sensor probe. The probe comprises a magnetic core support processed with pure iron or bulk amorphous ferromagnetic materials, wherein a central magnetic core leg and four magnetic core legs around the central magnetic core leg are arranged at the center of the magnetic core support; a magnetizing coil is wound on the central magnetic core leg; two detecting coils are respectively wound on two groups of magnetic core legs arranged diagonally; the magnetizing coil is connected with an alternating current power supply device; and the detecting coils are connected with a processing chip of the sensor through communication. The five-leg magnetic stress sensor probe has the beneficial effects that the anisotropic effects of magnetic properties of the detected points are converted to electric signals which can be conditioned via the magnetizing coil and the two detecting coils, and the electric signals are sent to the processing chip of the sensor to detect the load
