1 Planetary Magnetic Field Observations The Earth's magnetic field has been used for navigation since at least the eleventh century AD, but it was not until the seventeenth century that the source of this magnetic field was attributed to the Earth's interior. Namely, in 1600, William Gilbert ...
The B field predicted in section 2.1 between r = rs and AU for one solar rotation is then used to map the magnetic field lines between the Sun and Earth in the solar equatorial plane. For a given starting point r0 = (x0,y0) located between the Sun and Earth, a single magnetic ...

The two sets are analyzed independently because of the dawn-dusk asymmetry of the external magnetic field components of the data. Two scalar magnetic anomaly maps, the dawn and the dusk maps, are derived using the spherical harmonic expressions of the respective data set. The significant ...
The Earth’s magnetic field interacts with the Sun’s magnetic field. The interplanetary magnetic field (IMF) is a part of the Sun's magnetic field that is carried into interplanetary space by the solar wind. [http://pluto.space.swri.edu/image/glossary/cme.html]. The Earth’s magnetic fi...

is similar to the strongest anomalies on Earth (>100 A/m29). Reiner Gamma’s peak field strength at 20 km altitude is also similar to that at the Crisium antipode (Fig.1a)8. If the impactor was similar to a parent body of chondritic meteorites,XTRMmay range from ~0.1–1.5, with...
Surface magnetic fields of lithospheric origin on Mars may be of similar amplitude to the Earth’s main magnetic field. Although nonunique, the magnetization model of [24] predicts magnetization as large as 12 A/m for a 40-km thick lithosphere. Such large values imply that the magnetic ...
