Spectrograms obtained with a polarization analyzer at the Crimean Astrophysical Observatory are analyzed in order to determine the relationship between magnetic field strengths in sunspots and solar flare activity. Magnetic field strengths were measured by Zeeman splitting in eight different spectral lines at various levels of the solar atmosphere. Maximum magnetic field strength was recorded at a level of 400-600 km. The appearance of solar flares was found to coincide with increases in magnetic field strength in adjacent sunspots. The average rates of the variations occurring before, during, and after the flares were 356 (+ or - 75), -324 (+ or - 64), and -48 (+ or - 23) Gs per hour, respectively. Some possible explanations for the coincidences are discussed. 16 references.
