Experimental data obtained by the magnetometers on Mars 3 (1972) at heights of 1000 km on the day side and Mars 5 (1974) at heights up to 9000 km on the dusk and night sides during opposite polarities of the interplanetary magnetic field show that Mars has an intrinsic magnetic field. The magnetic moment of the Martian dipole is M ≈ 64Rm³ = 2.5·1022 G cm³, and the equatorial dipole field at the surface of the planet is 64 γ. The topology of lines of force on the day and night sides can be explained best if we assume that the magnetic dipole axis of Mars is tilted less than 15°–20° from the rotation axis. The bow shock position observed on the day side is in agreement with the hypothesis of an intrinsic Martian magnetic field.
This paper is devoted to a description of the problems related to the experiment and the experimental data concerning the field of the moon which were obtained during the flight of the second Soviet cosmic rocket.As a consequence of the analysis of the measuring apparatus' sensitivity threshold, according to measurement data in a weak geomagnetic field, some 45,000 to 60,000 km from the center of the earth, and of the analysis of noise level in the orbital space of the moon, coupled with measurements directly near the moon and up to 55 km from its surface, no notable magnetic field of the moon was revealed. It is estimated that the dipole magnetic moment of the moon must be smaller than 1/10,000 of the earth's magnetic moment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
