μr = l / (μ₀ * A * S) = 1 / (4π x 10^(-7) x 0.05 x 10,000) = 1591.5
A magnetic circuit consists of a coil of 200 turns, a core with a cross-sectional area of 0.02 m², and a length of 0.8 m. The air gap length is 0.5 mm. If the current through the coil is 8 A, find the magnetic flux. magnetic circuits problems and solutions pdf
The reluctance of the magnetic circuit is given by: μr = l / (μ₀ * A * S) = 1 / (4π x 10^(-7) x 0
S = MMF / Φ = 5000 / 0.5 = 10,000 A/Wb
Assuming μr = 1000, we get:
