<p>This study examines the entropy production occurring within the flow of an incompressible Jeffrey fluid through a sloping channel, incorporating the influences of hall current, Soret parameter, thermal radiation, and angled magnetic field. The derived governing equations are renovated into dimensionless governing equations through the utilization of similarity variables. The technique of spectral quasi-linearization method (SQLM) is applied to ascertain the solution. Graphs are employed to investigate and illustrate the impact of novel thermophysical parameters. With the use of tabular data, variations in skin friction, the Nusselt number, and the Sherwood number are also discussed. The findings indicate that increasing the Soret parameter, inclination angle, hall current, radiation parameter, and Jeffrey fluid parameter increases entropy generation. Conversely, entropy generation decreases with higher values of the inclination angle of the channel.</p>
