Abstract:
          We calculate the heating due to dissipation of magnetic fields generated inside protostellar disks, using three-dimensional MHD calculations. The spatial distribution and time variability of the heating within 1 AU of the young star and the consequences for the spectral energy distribution and chemical evolution are discussed.
