Abstract Applying external magnetic or electric fields, especially via a Riga plate, significantly improves flow efficiency by reducing friction and turbulence, enabling better management. This enhancement is particularly advantageous in enhancing the performance of engineered systems turbomachinery. Consequently, our research delves into dynamics low‐ionization fluid an extended infinite porous channel within rotating setup influenced Hall ion‐slip electromotive forces. The model examines various pressure gradient scenarios: impulsive (IPG), cosine (CPG), sine (SPG). We represent this through time‐varying partial differential equations solve these using Laplace transform (LT) method to obtain exact analytical solutions. Our carefully delineates dominance key factors on traits, employing graphical representations for IPG, CPG, SPG scenarios. observations reveal amelioration modified Hartmann number notedly enhances velocity components all types. A higher rotation parameter tends reduce primary velocity's shape profile, while secondary exhibits opposite trend. notably boosts with rise parameter, whereas decreases. Both velocities are generally IPG scenario than CPG SPG. Additionally, greater intensifies shear stresses cases, at lower plate being These findings offer substantial contributions sectors, including nuclear reactor technology, spacecraft propulsion, satellite operations, space exploration, aerospace engineering, so forth.
