                         ABSTRACT: In this work, we performed a theoretical development, 
                         self-consistent with recent models for the explosive source, 
                         applied to time delays between maximum emission frequencies in the 
                         microwave range and also with the issuance of these hard X-rays. 
                         The hypothesis working was the adoption of an increasing magnetic 
                         field during the solar flare, which contributed to growth, 
                         differential frequency, the microwave emission and delayed the 
                         time of maximum exploitation at low frequencies with respect to 
                         high and Microwave with respect to hard X-rays. It was found that 
                         such delays are compatible with an increase in the magnetic field 
                         of approximately 14%, assuming models thermal or non-thermal . 
                         Associating this variation of the magnetic field to the descent of 
                         thermal sources in the solar atmosphere found compatibility in 
                         velocity calculated speed characteristics of fronts driving 
                         anomalous models' thermal.",
