“…Further interpretation of this new model can be envisaged, in terms of dynamo cessation timing, ancient magnetizing field directions, or interactions with the solar wind to create so-called minimagnetospheres. Upcoming surface measurements of the Martian magnetic field by the InSight mission (Smrekar et al, 2019), or by future landers/rovers carrying appropriate instrumentation (Diaz-Michelena et al, 2017), will also help to constrain the surface intensity (even if this will be only locally) and to possibly monitor the magnetic field external variations (Mittelholz et al, 2017). nodes of these triangles.…”

While devoid of an active magnetic dynamo field today, Mars possesses a remanent magnetic field that may reach several thousand nanoteslas locally. The exact origin and the events that have shaped the crustal magnetization remain largely enigmatic. Three magnetic field data sets from two spacecraft collected over 13 cumulative years have sampled the Martian magnetic field over a range of altitudes from 90 up to 6,000 km: (a) Mars Global Surveyor (MGS) magnetometer (1997–2006), (b) MGS Electron Reflectometer (1999–2006), and (c) Mars Atmosphere and Volatile EvolutioN (MAVEN) magnetometer (2014 to today). In this paper we combine these complementary data sets for the first time to build a new model of the Martian internal magnetic field. This new model improves upon previous ones in several aspects: comprehensive data coverage, refined data selection scheme, modified modeling scheme, discrete‐to‐continuous transformation of the model, and increased model resolution. The new model has a spatial resolution of ∼160 km at the surface, corresponding to spherical harmonic degree 134. It shows small scales and well‐defined features, which can now be associated with geological signatures.

“…The use of a magnetic field as a variable stimulus was possible because, it application to the soil affected various parameters including conductivity [23,24], salinity [25,26], water quality [27,28], pH levels [29,30], evaporation [31], reduction in specific heat [32], and boiling point [33,34]. The principle of inducing a magnetic field [35,36] is used to provide a stimulus to the soil and the response to the induced voltage is captured using a receiver coil [37,38,39]. This principle of induction is carried out without contact with the soil.…”

This study proposes an increase in the measurement of soil water content with sensor characterization that can be integrated with the internet of things. The main contribution of this work is the improvement in measurement accuracy compared to measurements using a moisture meter. This is achieved through an electromagnetic approach using a pair of transceiver coils as a sensor. Determination of water content in the soil is carried out through the formulation of an equation model that connects the measured voltage on the receiving coil with the mass of water contained. It is known that the use of the equation model in the test data results in better accuracy with an error of 2.03% - 17.43%, compared to measurements using a moisture measuring device with an error of 13.21% - 32%. This equation model that uses the electromagnetic method provides an alternative solution for determining the soil water for wider land use so that can be used for internet of things application.
