The first idea of a magnetic cavity around a planet (the earth) was first postulated by Chapman and Ferraro already in the early thirties. The interest in studies of such a magnetic cavity which is caUed "magnetosphere” was reinforced since the accidentai discovery of the nonthennal Jovian decametric radiation (DAM) by Burke and Franklin (1955). However, it was Shain already in 1950 who first observed a radio émission at 18.3 MHz, but it was not yet attributed to Jupiter. This radiation indicated that Jupiter exhibits an intrinsic magnetic field, whereby the radio émission is caused by électrons spiralling around magnetic field Unes in the vicinity of the planet, finding confirmed by the discovery of the Jovian decimetric radiation and the earth’s Van Allen belts by the sateüites Explorer 1 and 3 in 1958.
