Due to the optical transitions between non-equidistant quantized Landau levels in an external magnetic field, graphene can be employed to dynamically tune the near-field radiative heat transfer (NFRHT). In this paper, we investigate the magnetic-field control of NFRHT between two graphene-based hyperbolic metamaterials (GHMs). We find that the magnetic field significantly regulates the NFRHT between two GHMs via modifying the intrinsic hyperbolic modes. Specifically, the radiative heat transfer in the low-frequency range is remarkably suppressed for chemical potential of graphene of 0.05 eV accompanied by the splitting of the heat flux peak with the increase in the magnetic field intensity. We also analyze the magnetoresistance effect related to the heat flux, which reaches 78.23% when H 1/4 7 T. Moreover, we find that the effect of the magnetic field on the hyperbolic modes of GHMs is much stronger for lower chemical potentials. We look forward to the applications of our findings in dynamical thermal management at the nanoscale.
