Abstract
Spectral numerical simulations of homogeneous incompressible magnetohy drodynamic turbulence at Reynolds mumbers up to about 500, are perform ed using a uniform grid of 180(3) collocation points. Strong vorticity and current sheets obtain both in the presence and in the absence of magnetic nulls. Contrary to vortex sheets in hydrodynamics, these stru ctures do not destabilize into filaments, but are locally disrupted. T hey are the main loci of kinetic and magnetic dissipations.
