Title:

We present Cluster multi-point measurements of burst bulk flows (BBF) in Earth’s magnetotail. When the satellite separation is small (of the order of 100 km), we can use the curlometer method to calculate local currents associated with BBF’s and possibly co-located dipolarization fronts. We present for the first time current calculations that are used to directly determine the jxB force at various regions of the BBF’s. The magnetic force is important, since together with the pressure gradient force it will determine the dynamics of the BBF’s as they enter the near-Earth region.
