Blahník, Z. Peroutka, J. Molnár, J. … SpletIn a transformer, magnetic flux is produced as a result of the varying electric field (i.e., alternating current). The change in magnetic flux in a transformer happens due to the variations in the current supplied by the AC source. AC source provides an alternating current that varies from negative to positive values in each cycle.
