Summary:The present invention relates to a device and a method for measuring a magnetic field, wherein a spin current is injected into a magnetic body that has magnetic anisotropy using a spin Hall effect occurring in a current applied to a conductor, and the degree of shift of hysteresis in the magnetic body is calculated while reversing the magnetization of the magnetic body by a spin torque such that an external magnetic field applied to the magnetic body can be measured precisely.
