    "abstract": "We investigate the transfer of energy from large scales to small scales in\nfully developed forced three-dimensional MHD-turbulence by analyzing the\nresults of direct numerical simulations in the absence of an externally imposed\nuniform magnetic field. Our results show that the transfer of kinetic energy\nfrom the large scales to kinetic energy at smaller scales, and the transfer of\nmagnetic energy from the large scales to magnetic energy at smaller scales, are\nlocal, as is also found in the case of neutral fluids, and in a way that is\ncompatible with Kolmogorov (1941) theory of turbulence. However, the transfer\nof energy from the velocity field to the magnetic field is a highly non-local\nprocess in Fourier space. Energy from the velocity field at large scales can be\ntransfered directly into small scale magnetic fields without the participation\nof intermediate scales. Some implications of our results to MHD turbulence\nmodeling are also discussed.",
