Short summary
The Sun's magnetic field is carried across space by the solar wind – a hot plasma stream of ions and electrons – forming the interplanetary magnetic field (IMF). The IMF can introduce asymmetries in the Earth's magnetic field, giving plasma flowing within it a direction dependent on IMF orientation. Electric currents in near-Earth space can also influence these plasma flows. We investigate these two competing mechanisms and find that the currents can prevent the IMF from controlling the flow.
