Investigating Time Volatility Magnetic Field of the Jovian Moon: Callisto Using Magnetometer Sensor

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.
