<p>In this paper, a new micromagnetorotative flow model is presented for the analysis of heat transfer in the framework of micropolar continuum. The heat transfer analysis over a moving liquid surface is based on the influence of micromagnetorotation (MMR). To the best of authors’ knowledge this description of the dynamics is not present in literature. MMR is a naturally occurring phenomena in flows over moving micropolar liquid surfaces that are subjected to externally applied magnetic filed. This magnetization effect has been neglected in previously discussed literature on the topic within the framework of micropolar flows over moving liquid surfaces. The derived initial boundary value problem is implemented in MATLAB and is numerically solved. The results obtained are validated through the computation of skin-friction and Nusselt numbers against physical parameters by comparing with computed solutions through bvp4c. The study explores the impact of magnetization and microstructural effects on fluid flow and heat transfer characteristics. It is observed that increasing the MMR effect and micro-inertial parameter significantly reduces the skin-friction coefficient due to enhanced flow uniformity and decreased surface resistance. In the absence of MMR, greater microstructural resistance to heat transfer leads to a decrease in the Nusselt number with rising Cosserat numbers. Conversely, under the influence of MMR, the Nusselt number increases due to synergistic effects. The heat transfer rate improves with higher magnetization relaxation time, resulting in thinner thermal boundary layers and more efficient convective heat exchange. Additionally, MMR enhances thermal mixing and alters flow dynamics, contributing to a thicker hydrodynamic boundary layer and a consistently thinner thermal boundary layer. Increased micro-inertia further reduces thermal boundary layer thickness by promoting microscale mixing and faster heat redistribution.</p>
