Comments on: Effects on magnetic field in squeezing flow of a Casson fluid between parallel plates

Ahmed et al. (2017) examined the dynamics of a Casson fluid squeezed between two parallel plates where the fluid was also subjected to a constant magnetic field. Therein they claimed to derive a fourth-order boundary value problem from the general governing equations whose solution could be used to form the fluid’s velocity components. The purpose of the present note is to place the ideas in Ahmed et al. (2017) under scrutiny. In doing so we raise some doubts regarding some of the forms therein.
