This study involves an MHD rotating nano fluid ow over a stretching surface. Base fluid, via water, and kerosene liquids are employed with Barium Ferrite BaO. 6Fe2O3 nanosize particles in our investigation, which are known as ferro fluid. Governing equations involving partial derivatives of the problem are established and converted into dimensionless forms of ordinary derivatives by means of suitable and compatible similarity transformations. The transformed system of equations is tackled by a reliable numerical scheme as a midpoint integration pattern together with an extrapolation scheme of Richardson. This numerical pattern is launched in maple software. Variations in ow, velocity and temperature due to the involved parameters are recorded via graphs and tables. The authors' targeted quantities, like local tangential stress and heat transfer rate at the wall, are calculated for nano fluid. Heat transfer rate at surface level z = 0 rises with a rise in solid nanoparticle ', but it falls with a rise in magnetic factor M, spin factor , and Eckert number Ec. The higher heat transfer rate is recorded in the case of kerosene grounded Ferro fluid. Base fluid plays a vital role in determinations. Water is preferred as the base fluid for significant outcomes.
