A tight-binding model is diagonalized to elucidate the magnetoelectronic properties of bulk graphite. This method reveals far more significant results than previous treatments based on simplified effective-mass approximation. The wave functions are explicitly presented and their spatial distributions appropriately characterize the Landau subbands. The calculated density of states and optical absorption spectra agree well with experiments. Our accurate results enable one to assess to what degree the bulk graphite resembles monolayer and bilayer graphenes. The inclusion of all interlayer coupling leads to rich spectral features awaiting future experimental verifications.
