摘要：
The effect of explosive processes (EPs) in active regions (ARs) in the Sun on characteristics of the magnetic field in the umbra of sunspots forming the AR is studied. By EPs we mean solar flares accompanied and not accompanied by the formation of coronal mass ejections (CMEs). The changes in the maximum B-max and average < B > values of magnetic induction within the sunspot umbra under the action of different EP types are analyzed. In particular, we try to clarify which manifestation of the EP influences magnetic properties of the sunspot umbra more significantly, the solar flare or the CME. Based on visual analysis of changes in the magnetic field in all spots of the analyzed ARs during the explosive process, the conclusion is made that the EP exerts the strongest influence on magnetic properties of the sunspot umbra in ARs in which the EP included a powerful solar flare and formation of a fast CME.
