### U, \(\theta\) and \(\phi\) Profiles to Check Accuracy of Numerical Data  
The fluid velocity, temperature and magnetic profile were mapped against four values of reduced-gravity parameter Rg = 0.1, 0.3, 0.5 and 0.7 at both positions \(\alpha=\pi/2\) and \(\pi\) around a non-conducting cylinder, as shown in Figure 2a-c. The fluid velocity and magnetic profile showed maximum behavior at \(\pi/2\) station as Rg was increased but dimensionless temperature of the fluid attained maximum magnitude as Rg was decreased at \(\pi\) station in Figure 2a,b. The asymptotic analysis of the numerical results for Pr = 7.0 (water) in the case of \(U\), \(\theta\) and \(\phi\) were prominent. Physically, this could be because an increase in the decreased gravity parameter impacts the fluid flow's driving potential along a thermal, non-conducting horizontalcylinder. The geometric representations of the velocity distribution, temperature, and magnetic field profile are demonstrated in Figure 3a-c against different choice values of the Prandtl parameter Pr in the influence of reduced gravity and magnetohydrodynamic effects at both locations of the horizontal non-conducting cylinder. In Figure 3a, a velocity graph shows a sharp increase to its peak value for lower Pr = 0.1 at \(\pi/2\) position then a decrease to its asymptotic value. It is depicted that the temperature of the fluid and magnetic field was reduced for maximum Pr = 7.0 at both stations for fixed parameter \(\lambda\) in Figure 3b,c. The reason for this is because the fluid's thermal conductivity decreases while intermolecular interactions diminish. The geometrical significance of velocity distribution, temperature, and magnetic field profile is depicted in Figure 4a-c against four choice values of \(\lambda\) with reduced gravity and magnetohydrodynamics effects along the non-conducting geometry. The velocity achieved the maximum value at the \(\pi/2\) location with a certain height as \(\lambda\) was enhanced but it was depicted in a similar way at the \(\pi\) location for all values of \(\lambda\). The magnetic profile and temperature were enhanced with prominent variations for a larger value of \(\lambda=\) 7.0 with lower reduced gravity effects. The magnetic effects far from the surface were reduced for a lower \(\lambda=1.0\) in a similar way at both locations. From the above geometrical plots, it was depicted that the gained numerical outcomes were in prominent agreement and satisfied their boundary conditions. Transient Shapes of \(\tau_{s}\), \(\tau_{t}\) and \(\tau_{m}\) Profiles to Check Accuracy of Numerical Data  
The impact of the physically emerging parameters on the transient skin-friction \(\tau_{s}\), oscillating heat transfer \(\tau_{t}\) and oscillating current-density \(\tau_{m}\) around a horizontal non conduction cylinder was drafted for the more appropriate physical dimensionless parameters at \(\alpha=\pi/2\) and \(\pi\) positions. Figure 5a-c display the reduced gravity effects on unsteady numerical results. Transient \(\tau_{t}\) and transient \(\tau_{m}\) rate show the maximum amplitude of fluctuation in Figure 5b,c at both \(\pi/2\) and \(\pi\) stations in the presence of reduced gravity. In the above-displayed plots, a smaller and decreasing behavior in \(\tau_{s}\) is illustrated under the influence of reduced gravity and mixed-convective effects in Figure 5a. It was expected that an effective change in the acceleration of gravity was produced on fluid with different density variations due to buoyancy forces. The influence of the Prandtl number \(\mathrm{Pr}\) is plotted in Figure 6a-c, where Figure 6a is devoted to expressing the diverse choices of \(\mathrm{Pr}=1.0,\ 3.0\) and \(7.0\) on oscillatory \(\tau_{s}\), Figure 6b demonstrates the oscillating \(\tau_{t}\), and Figure 6c an oscillatory current density. It was discovered in Figure 6a that the rise in \(\mathrm{Pr}\) gave a decrease in the amplitude of skin friction at \(\pi\) station but increased at the \(\pi/2\) position.
