An iron ring of circular cross-section of \(5 \times 10^{-4}\) m² has a mean circumference of 2 m. It has a saw-cut of \(2 \times 10^{-3}\) m length and is wound with 800 turns of wire. Determine the exciting current when the flux in the air gap is \(0.5 \times 10^{-3}\) Wb. Given μr of iron = 600 and leakage factor = 1.2. Assume the areas of air gap and iron are the same.
