review text: Summary: Numerical study has been performed to investigate the fluid flow through a rotating rectangular straight duct in the presence of magnetic field under various flow conditions. Spectral method is applied as a main tool for the numerical calculation technique, where the Chebyshev polynomial, collocation method and the Newton-Raphson method are also used as secondary tools. The magnetohydrodynamic incompressible viscous steady fluid flow through a straight duct of rectangular cross-section rotating at a constant angular velocity about the centre of the duct cross-section is investigated to examine the combined effects of magnetic parameter (\(M_g\)), rotational parameter (\(T_r\)), pressure driven parameter (\(D_n\)) and aspect ratio (\(\gamma\)). One of the interesting phenomena of the flow is the solution curve and the flow structure. The flow structures in case of rotation of the duct axis, the pressure driven parameters with large magnetic parameters well as large rotational parameters are examined while other parameters remain constant. The calculations are carried out for \(5\leq M_g\leq 50,000\), \(50\leq T_r\leq 100,000\), \(D_n=500\), 1,000, 1,500 and 2,000 where the aspect ratio 3.0.
