Kink oscillations of coronal loops as a tool for the determination of coronal magnetic field

We develop a new method for the determination of the absolute value of the magnetic field strength in coronal closed magnetic structures, based on the analysis of flare-generated oscillations of coronal loops. Interpretation of the quasi-harmonic oscillations observed in terms of global standing kink waves allows to connect the period of the oscillations and the loops length with the magnetic field strength in the loops. Improved diagnostic of the loop length, the oscillation period, and the plasma density in the loop will significantly improve the method's precision
