So if the spacecraft descends below stationary altitude, where the speed of the magnetized plasma is lower than the speed of the spacecraft, the natural output of an EDT is a drag force, along with usable electrical power from the tether current.

• 因此如果太空船下降到同步轨道之下，磁化电浆的速率比太空船的速率低，则EDT自然产生拖曳力，以及缆索电流中可利用的电能。
