The magnetic filed is assumed to have only constant axial (H_Zo&nbsp;= constant) and variable azimuthal (H_qo&nbsp;= r^1/2&nbsp;H_z) components, taking an initial density distribution as r₀&nbsp;= r&#39;e^-lr, where r&#39; is the density on the axis of symmetry and l is a non-dimensionalising constant. Cases of reverse trends of variation of flow variables with inclusion of e.o.d have been highlighted.&nbsp;<br /> &nbsp;</p> https://ultraphysicalsciences.org/paper/1290/ Hydromagnetic shock waves Effects of overtaking disturbances
