<p>The current work presents the magnetohydrodynamics effects of a non-isothermal viscoplastic fluid based on the coating analysis with a flexible blade. The complexity of the interconnection of heat transfer and rheological material properties with the fluid dynamics attracts the scientist and researchers across various scientific fields. The complexity of a non-isothermal viscoplastic fluid provides an additional insight into the process of blade coating when combined with flexible blade. An analysis of coating process for viscoplastic fluid has been established taking into account the blade flexibility, fluid rheological properties, temperature variations, and phenomena. The lubrication approximation theory simplifies the equations of motions and non-dimensional using suitable transformations. The analytical solutions of the constitutive equations are calculated and numerically compared for various quantities of interest. The graphical results are presented for comparison purposes for velocity profile, gradient, volumetric flow rate, temperature distribution and pressure. This research promotes the future exploration and innovative insight in the area of coating using non-isothermal viscoplastic fluids and novel investigations in non-Newtonian fluid dynamics.</p>
