The magnetic field in BHR 71 was mapped from 25 stars. By using a simple 2D parabolic function, the plane-of-sky magnetic axis of the core was found to be $\\theta_{\\rm mag} = 125^{\\circ} \\pm 11^{\\circ}$. The plane-of-sky mean magnetic field strength of BHR 71 was found to be $B_{\\rm pos} = 8.8 - 15.0$ $\\mu$G, indicating that the BHR 71 core is magnetically supercritical with $\\lambda = 1.44 - 2.43$.
