The time of formation and decay of the supergranulation cells between which the magnetic tube is situated vertically defines its torsional oscillation period. Amplitudes of oscillation components were calculated. For a radial velocity of plasma motions in supergranules 0.2 km/s and plasma density of 2*10^-3 kg/m^3 magnitudes of torsional oscillation amplitudes are in agreement with those obtained from observations.
