QUESTION 5
The following figure shows a ferromagnetic core and the dimensions are: the mean path length \((a-b) = 0.16\) m, \((b-c) = 0.1\) m, \((c-d) = 0.16\) m, \((d-e) = 0.04\) m, \((f-a) = 0.05\) m,
and air gap length =0.5 m. The relative permeability of the core = 7,106, and the cross-sectional area of the core = 0.00121 m$^2$.
Find the reluctance of the ferromagnetic core ($\mathcal{R}$)?
