  • Description: Fig. 1 show that the micropolar nanofluid between two parallel plates under the influence of magnetic and electric field in a rotating system is investigated. The nanofluid flow between two parallel plates is taken under the influence of Hall current. The flow of micropolar nanofluid has been assumed in steady state. [Display omitted] •The Micropolar nanofluid with electrical MHD is modeled and solved in a rotating system between parallel plates. The fluid flow is considered in three dimensions.•The effect of Hall current applied to the nanofluid flow phenomena.•Skin friction co-efficient hat flux and mass flux for engineering interest are calculated through Tables.•The impact of the physical parameters is observed on the velocity, micro rotation, temperature and concentration fields respectively.•The high nonlinear coupled system of differential equations is tackled through HAM. The current research aims to examine the combined effect of magnetic and electric field on micropolar nanofluid between two parallel plates in a rotating system. The nanofluid flow between two parallel plates is taken under the influence of Hall current. The flow of micropolar nanofluid has been assumed in steady state. The rudimentary governing equations have been changed to a set of differential nonlinear and coupled equations using suitable similarity variables. An optimal approach has been used to acquire the solution of the modelled problems. The convergence of the method has been shown numerically. The impact of the Skin friction on velocity profile, Nusslet number on temperature profile and Sherwood number on concentration profile have been studied. The influences of the Hall currents, rotation, Brownian motion and thermophoresis analysis of micropolar nanofluid have been mainly focused in this work. Moreover, for comprehension the physical presentation of the embedded parameters that is, coupling parameter N1 , viscosity parameter Re, spin gradient viscosity parameter N2, rotating parameter Kr, Micropolar fluid constant N3, magnetic parameter M, Prandtl number Pr, Thermophoretic parameter Nt, Brownian motion parameter Nb, and Schmidt number Sc have been plotted and deliberated graphically.
