The Hall effects on unsteady MHD plasma behaviour of a rotating environment with oscillating pressure gradient in the presence of a transverse magnetic field have been studied. The solution in a dimensionless form contains five pertinent flow parameters, viz., 'alpha'm, E, P, 'omega' and m are, respectively, the magnetic interaction parameter, the Ekman number, the magnetic Prandtl number, the inertial frequency and the Hall current parameter. A new approach is based on the plasma behaviour in the electromagnetic field in a rotating environment which corresponds to inertial frequency over the oscillating pressure gradient. Eventually, the dominance of inertial frequency is experienced by the mechanism; the whole system stops due to the absence of inertial frequency of a rotating environment.
