According to some previous topic that i have learnt , If a magnetic circuit has 1 wrapped then will have 2 reluctances which is reluctance of the iron core ( assume it is ferromagnetic core), and another one is recluctance in the wrapped, so i dont understand what your meant ?No, you have only one reluctance in this case. So try to calculate the reluctance base on the core dimensions given to you. Can you do it?
Thank you very much, I get it nowYou understand it wrongly. In your example, you have only one path for magnetic flux to "flow". Hence only one reluctance value.
R = le/(μ*Ae)
le - Effective magnetic path length
Ae - Effective core area
μ = μo * μr
