Abstract EN
The effect of a nonuniform magnetic field on the gravitational instability of a nonuniformly rotating infinitely extending axisymmetric cylinder in a homogenous ferromagnetic medium has been studied.
The propagation of the wave is allowed along radial direction.
A general dispersion relation, using the normal mode analysis method on the perturbation equations of the problem, is obtained.
It is found that Bel and Schatzman criterion determines the gravitational instability of this general problem.
Thus, it appears that the effect of non-uniform magnetic field on the gravitational instability as discussed by (Dhiman and Dadwal, 2010) is marginalized by the magnetic polarizability of ferrofluid.
