Unsteady mixed convectional boundary layer flow of Casson nanofluid having magnetic( Fe3O4) and nonmagnetic(
Al2O3) nanoparticles suspension within two different types of base fluids, water(Newtonian) and
Sodium Alginate(non-Newtonian), which incorporates viscous and ohmic dissipation effects over a permeable
nonlinear stretching sheet with magnetic field effects. Some suitable non-dimensional similarity transformations
are applied to convert the governing PDEs into a system of nonlinear coupled ODEs and then solved
by differential transformation method(DTM) association with Pade-approximation. To validate the present
results for limited cases, a comparison was made with previously existing literature and found to be in well
agreement. The impact of radiation, internal heat sink/ source, viscous and ohmic dissipation was discussed for
magnetic and non-magnetic nanofluid categories by tabular and graphical demonstrations. We have presented
the tabular results of various emerging parameters to discuss the nature of skin friction, Nusselt and Sherwood
numbers. It was also observed that performance of non-Newtonian(Sodium Alginate) fluid in heat and mass
transfer is better than Newtonian(water) based fluid but no major difference was seen in heat and mass transfer
when comparison was made with Magnetic and Non-magnetic nanoparticles
