Sumario:[EN] Recent progress in the study of the quiet-day geomagnetic field variations having the ionosphere as a source is reviewed. This represents an old topic in the history of Geomagnetism and Aeronomy, and since the purpose of the paper is to provide the reader with an overall description of its present understanding, no matter whether a particular subtopic has been revisited in the last decade or not, the degree of updating is variable throughout the review. Special attention is paid to the advances in the modeling techniques and to the possible explanations to the variability of the mid-latitude ionospheric current system.
