The reluctance offered by a magnetic circuit consisting of two parallel paths acted upon by the same magneto motive force is equal to half the reluctance of each path.

Key Points F4 Madhuri Engineering 18.01.2023 D4

In the above figure shown a parallel magnetic circuit consisting of two parallel magnetic paths ACB and ADB acted upon by the same m.m.f. Each magnetic path has an average length of 2 (l1 + l2 ).

The flux produced by the coil wound on the central core is divided equally at point A between the two outer parallel paths.

The reluctance offered by the two parallel paths is = half the reluctance of each path.
