...‐Raphson shooting method along with fourth‐order Runge‐Kutta integration algorithm. Findings It was found that magnetic field retards the fluid motion due to the opposing Lorentz force generated by the magnetic field. Both the magnetic field and the Eckert number tend to enhance the heat transfer...
