AB - This study explains the entropy process of natural convective heating in the nanofluid-saturated cavity in a heated fin and magnetic field. The temperature is constant on the Y-shaped fin, insulating the top wall while the remaining walls remain cold. All walls are subject to impermeability and non-slip conditions. The mathematical modeling of the problem is demonstrated by the continuity, momentum, and energy equations incorporating the inclined magnetic field. For elucidating the flow characteristics Finite Element Method (FEM) is implemented using stable FE pair. A hybrid fine mesh is used for discretizing the domain. Velocity and thermal plots concerning parameters are drawn. In addition, a detailed discussion regarding generation energy by monitoring changes in magnetic, viscous, total, and thermal irreversibility is provided. In addition, line graphs are created for the *u* and *v* components of the velocity profile to predict the flow behavior. Current simulations assume the dimensionless representative of magnetic field Hartmann number *Ha* between 0 and 100 and a magnetic field inclination between 0 and 90 degrees. A constant 4% volume proportion of nanoparticles is employed throughout all scenarios.
