Query: Role of a magnetic field in the context of inhomogeneous gravitational
  collapse   Magnetic fields are found to have an inherent capability of acting against
gravity. An important question posed in the literature is whether presence of a
magnetic field can alter the dynamics of a gravitational collapse and prevent
the final formation of a singularity. Promising conclusions regarding this have
been found in a few recent works considering nearly homogeneous models.
However, whether this can happen in realistic collapse scenarios is still not
very clear and remains an open problem. In the present work we investigate the
role of magnetic fields in the evolution of inhomogeneous cylindrically
symmetric models. We use an approach based on the Raychaudhuri equation for
such an analysis. We show that it is quite possible for the magnetic field to
avert the gravitational collapse in these models.
