The magnetic circuit shown in figure below is built up of solid iron cross section, 1x1cm2. Each air gap is 1 mm wide. For this type of air gap, the effective cross-section of the air may be taken as 1.2 x that of iron path to allow for fringing. Two different grades of iron are used. When a coil having 2000 turns is wound on part B, and a current of 0.5A is applied to it, the relative permeability of part A is measured as 500, and of part B as 1000.

a) Calculate the Reluctance of part A

b) Calculate the Reluctance of part B
