magnetic core and in small air gaps which arise when the separate core halves forming a closed magnetic loop core come together. In the equivalent circuit of a real transformer, mutual inductance appears in parallel with the primary windings only. The energy stored in the magnetization inductance is a function of the volt-seconds per turn
