The effect of the induced magnetic field on the motion of Eyring-Powell nanofluid Al2O3, containing gyrotactic microorganisms through the boundary-layer is investigated. The viscoelastic dissipation is taken into consideration. The system is stressed by an external magnetic field. The continuity, momentum, induced magnetic field, temperature, concentration, and microorganisms equations that describe our problem are written in the form of 2-D non-linear differential equations. The system of non-linear PDE is transformed into ODE using appropriate similarity transformations with suitable boundary conditions and solved numerically by applying the NDSolve command in the MATHEMATICA program. The obtained numerical results for velocity, induced magnetic field, temperature, the nanoparticles concentration, and microorganisms are discussed and presented graphically through some figures. The physical parameters of the problem play an important role in the control of the obtained solutions. Moreover, it is obvious that as Grashof numbe increases, both the velocity, f ?, and the induced magnetic field, h?, increase, while, the reciprocal magnetic Prandtl number, A, works on decreasing both f ? and h?. As Eckert number increases the temperature increases, while it decreases as the velocity ratio B increases.
