Earth electromagnetism

This is a summary of the activities of the Geophysics Department of the Geodetic and Geophysical Institute in the framework of the Scientific School Earth Electro- magnetism. Ten reports cover the most important topics and emphasize intercon- nections between the different phenomena. The topics include interplanetary space, magnetosphere and ionosphere, electromagnetic waves in a wide spectrum, and elec- tromagnetic induction, also within a wide range of frequencies and applications. Geomagnetism, especially the Sz ́ echenyi Istv ́ an Geophysical Observatory Nagycenk with a lot of different recordings of electromagnetic parameters play important roles in most topic
