Abstract : A Riga plate is an electro-magnetic instrument working with anodes and magnets on plates. The Riga plate has numerous advantages in geophysical sciences, the field of engineering, sensors,and astrophysics.The present work investigated the transitory Electromagnetohydrodynamic radiative squeezing unsteady motion of Casson nanofluid through a parallel channel impacted by the Riga plate with endothermic/exothermic chemical processes and porous media. The PDEs transform into non-linear ODEs using the appropriate similarity transformations. The RKF-45 method and Shooting techniques are utilized to compute the solutions to these non-linear ODEs and related boundary conditions. The consequences of non-dimensional parameters on the corresponding profiles are illustrated graphically. And also studied some significant engineering coefficients. The primary findings of the present study are a rise in the thermal relaxation time parameter, temperature increases for the exothermic chemical reaction case, and opposite behavior in the endothermic chemical reaction case. Enhancement in activation energy parameter, the temperature drops for exothermic and increases for the endothermic case. The value of the modified Hartmann number rises, the velocity profile is also increased in the lower plate and the opposite behavior in the upper plate. Increase in Biot number, temperature decreases in the exothermic case and increases in the endothermic case.
