: Influence of Dufour on Instability The present research investigates the rotational impact on the magnetic parabolic flow through an accelerated vertical plate in a magnetic field when the temperature and the rate of mass diffusion remain constant. The fluid under consideration conducts electricity. The solutions for the profiles of velocity, temperature, and concentration have been found using the Laplace transform method. Discussion of the findings can be assisted by graphs generated for a variety of factors, including the thermal Grashof number, the mass Grashof number, the Prandtl number, the Hartmann number, the Schmidt number, the Dufour number, the time of the magnetic field, and the acceleration parameter. As the estimated heated Grashof number (or mass Grashof) rises, so does the velocity. It is also verified that a decrease in the magnetic field M results in an increase in velocity.
