Hall current ionosphere
WebSuch a current, called a Hall current (after the Hall effect), is always present when an electric field is applied to a conductor containing a magnetic field. The electrical … WebA common measure for the quiet time ionosphere are median values of the ionosphere during one solar rotation period (27 days). The deviation of the ionosphere from the quiet values (median) are considered as ionospheric perturbations. The service provides a map of Europe presenting the current level of ionospheric activity (perturbations of foF2).
