At the magnetic dip equator, where the geomagnetic field is horizontal, this electric field results in an enhanced eastward current within ± 3 degrees of the magnetic equator, known as the equatorial electrojet.
At the magnetic dip equator, where the geomagnetic field is horizontal, this electric field causes a heightened eastward current within ± 3 degrees of the magnetic equator, known as the equatorial electrojet. This phenomenon shares similarities with other electrical currents in nature.
