We investigate the effect of a magnetic field on the thermal properties of phonons in graphene. We calculate the heat capacity of the phonons using a generating functional technique, and find a new phenomenon that a staircase-like behaviour appears in the change of the phonon heat capacity as well as the thermal conductivity with the temperature. The width and height of each step are related to the magnetic field and the temperature. This may provide a scheme of controlling the thermal properties of graphene by a weak magnetic field.
