We present a modification to our spacetime-parallel method, which enables its application to the Eddy-current equation. The key ingredient is applying a nodal auxiliary space correction not in each time step, but globally over the whole time domain. We proceed with a practical implementation of said method and present convergence rates. These experiments further detect the constant for the coarsening rule, which is used to determine, if the coarse grid correction should use a coarser spatial mesh.
