Abstract: The equation of small oscillations for a circular cross-section plasma column with a helical magnetic field is received. It is shown that this equation is equivalent to Hain — Lust equation, however has simpler appearance. The given equation allows to receive a number of earlier known results, and to analyse also transversal small-scale MHD perturbations: the criterion of stability of these modes, expression for the maximum increment are obtained, areas of propagation of both stable and unstable modes are defined. The obtained results can be used for interpretation of behavior of solar magnetic tubes. |
| Keywords: equation, Hayn-Lust's equation, helical magnetic field |
