The figure shows a coil with a sheet iron core with unlimited magnetic penetration and a rectangular cross-section. The coil is made of insulated copper wire with specific resistance p. Coil coefficient (le the ratio of the net cross-sectional area of copper to the total cross-sectional area of the coil) is equal to fw. A) Find the mean length (1) of both windings.
