title = "Shape oscillations of a slightly viscous liquid metal drop in a strong magnetic field",
abstract = "We analyse small-amplitude free oscillations of a weakly viscous and electrically conducting drop in a strong uniform DC magnetic field. An asymptotic solution is obtained showing that the magnetic field does not affect the shape eigenmodes, which are the spherical harmonics as in the non-magnetic case. The magnetic field, however, changes the frequency spectrum of oscillations. As the droplet oscillates, the liquid moves as solid columns aligned with the magnetic field. Two types of such oscillations are possible: longitudinal and transversal to the magnetic field. Oscillations are weakly damped by the magnetic field - the stronger the field, the weaker the damping, except for the axisymmetric transversal modes. The latter are strongly over-damped because they are not compatible with purely columnar liquid flow.",
