Large-scale magnetic regions evolve their photospheric structure relatively slowly during their lifetime for many months. Horizontal transport velocities of the magnetic flux responsible for the evolution are inferred for each whole Carrington rotation for time interval of the last three activity cycles Nos. 21 22 and 23 i.e. from the year 1976 to the present. In the paper it is assumed that the causes of the departure of the magnetic field in solar atmosphere from current free configurations are magnetic transport velocities of the opposite polarities in photosphere. For each Carrington rotation the value of the current helicity as well as an available magnetic energy were computed and localities with both enhanced values were selected. A possible role of the large-scale flow and magnetic field in the process of the current helicity formation is discussed. Changes of the latitude profile of the helicity as well as the hemispheric dependence of the helicity sign during the activity cycle are described.
