Mercury's magnetic field is approximately a magnetic dipole, apparently global, [8] on the planet of Mercury. [9] Data from Mariner 10 led to its discovery in 1974; the spacecraft measured the field's strength as 1.1% that of Earth's magnetic field. [10] The origin of the magnetic field can be explained by dynamo theory. [11]
7 maj 2015 · From orbital vector magnetic field measurements of Mercury taken by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft at altitudes below 150 kilometers, we have detected remanent magnetization in Mercury’s crust.
14 gru 2012 · Although the field is primarily dipolar, and of the same polarity (termed normal polarity) as Earth's field, Mercury's surface magnetic field strength is only about 1% that of Earth's [Ness et al., 1974], corresponding to a dipole moment that is smaller by a factor of about 1000.
11 sty 2024 · Mercury Magnetosphere. MESSENGER Model 2010. Dipole field strength: 0.002 Gauss-Rh 3 Dipole tilt to rotational axis: 0.0 degrees Dipole Offset: 0.17 Rh Surface (1 Rh) field strength: 0.0025 - 0.007 Gauss. Rh denotes Mercurian model radius, here defined to be 2,440 km.
14 sty 2019 · We show that the present models produce magnetic fields similar in morphology and strength to that of Mercury. The dynamo-generated fields act on the flow to force interaction between...
7 gru 2012 · Key Points. Mercury's magnetic field is an axialy aligned dipole offset 0.2 RM to the north. Additional high-degree structure is less than 7% of the offset dipole. The result is consistent with a deep dynamo and a nonconvecting outer layer. 1. Introduction.
30 wrz 2011 · We consider the magnetic field (B) in cylindrical Mercury solar orbital (MSO) coordinates (ρ, ϕ, Z) MSO, where ZMSO is positive northward, ϕ MSO is zero at the subsolar point and increases toward dusk, and ρ MSO is positive outward parallel to the equatorial plane.
