• Impact of magnetic field in three-dimensional flow is investigated.
• Thermal radiation effects are accounted in the energy equation.
• Convective type conditions of temperature and concentration are imposed.
• The governing nonlinear problems are computed for the convergent approximate solutions.
• Influences of different parameters are shown and examined.

This article investigates the convective heat and mass conditions in three-dimensional flow of an Oldroyd-B nanofluid. The stretched flow is electrically conducting in the presence of an applied magnetic field. Thermal radiation effects are accounted in the energy equation. The governing nonlinear problems are computed for the convergent approximate solutions. Influences of different parameters on the dimensionless temperature and nanoparticle concentration fields are shown and examined. Quantities of physical interest namely local Nusselt and Sherwood numbers are computed and analyzed numerically. Comparison in a limiting case is made with the previous published result and an excellent agreement is noted.
