Abstract
The cyclic variations in the quadrupole component of the solar magnetic field is studied in tensor description. The results are consistent with the classical description of the quadrupole using spherical functions, and the mathematical apparatus of tensor algebra allows one to compare the observed changes in the magnetic quadrupole and the changes predicted by the dynamo theories. In conclusion, the quadrupole properties can be adequately described by solar dynamo models that assume deviations from the dipole symmetry without the independent excitation of the quadrupole symmetry modes.
