Abstract The paper presents a novel study to examine the irreversibility of quadratically mixed convective electro-magnetohydrodynamic (EMHD) flow couple-stress hybrid nanofluid (CSHNF) with variable properties in vertical porous channel. channel walls are exposed an applied electric field effect and uniform transverse magnetic field. considered is ethylene glycol ( C 2 H 6 O ) base multi-walled carbon nanotubes MWCNT silver Ag nanoparticles (NPs), assuming fluid be state thermal equilibrium following Tiwari-Das model. potential applications can microfluidics nanofluidics, particularly developing cooling technologies, EMHD pumps, high-end microelectromechanical systems (MEMS), lab-on-a-chip (LOC) devices used bioengineering. A constant pressure gradient acting direction buoyancy under quadratic Boussinesq approximation drive flow. governing momentum energy equations nondimensionalized using pertinent dimensionless parameters solved by semi-analytical homotopy analysis method (HAM). entropy generation Bejan numbers derived irreversibilities system. To investigate rate shear stresses heat transfer, skin friction coefficients Nusselt on determined. emphasizes influence nanoparticle concentration electromagnetic dynamics, temperature distribution, system presence media. It reveals enhancement velocity degradation for higher concentrations. In contrast, both reduce electrical strength. With joule heating convection, attained low transfer irreversibility. However, it reduces concentration, strength, porosity, conductivity dominance
