Abstract
The dynamic structure of the magnetosphere present in the Jovian environment can be explored by detecting magnetic field of the Jovian moon. The present study provides the evidence of magnetic field variation in the Jovian moon (Callisto). The raw data of magnetic field (.lbl format) obtained from planetary plasma interactions node, at NASA’s portal has been used. Magnetic field vector and time series data were used to determine the magnetic field of the Callisto. Magnetic variation in the moon was assessed using contour plots. MATLAB has been used to generate the time series magnetic graphs of the Callisto moon. Findings revealed that magnetic field varied with changes in time in Callisto. Reverse swept in the magnetic field was observed towards the magneto tail of Jupiter. The methodology adopted in this study can be extended to assess the magnetic field of other Jovian moons also.

Modeling the Jovian current sheet and inner magnetosphere

TL;DR: In this article, a model of the azimuthal current sheet by a finite thickness annulus of inner radius 5 Jovian radii, 5-Jovians thickness, and extending to about 50 Jovians radii provides detailed fits of the vector magnetic field perturbations observed in relation to the planetary field.

A geomagnetic field spectrum

TL;DR: In this paper, a spherical harmonic model of the earth's internal magnetic field of degree and order 23 is derived from selected MagSat data, and its power spectrum, computed with terms developed by Mauersberger (1956) and Lowes (1974), is found to exhibit a change of a slope at n = 14 which is interpreted as an indication that the core field dominates at values lower than 13 while the crust field dominates above a value of 15.

The Juno Magnetic Field Investigation

TL;DR: The magnetometer sensors are controlled by independent and functionally identical electronics boards within the magnetometer electronics package mounted inside Juno's massive radiation shielded vault as mentioned in this paper, and the imaging system sensors are part of a subsystem that provides accurate attitude information near the point of measurement of the magnetic field.

The near‐Earth magnetic field at 1980 determined from Magsat data

TL;DR: In this paper, the MAGSAT spacecraft data from November 1979 through April 1980 and from 91 magnetic observatories for 1978 through 1982 were used to derive a spherical harmonic model of the Earth's main magnetic field and its secular variation.
