Φ = MMF / S = 1600 / 5969 = 0.268 Wb

S = l / (μ₀ * μr * A)

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

μr = l / (μ₀ * A * S) = 1 / (4π x 10^(-7) x 0.05 x 10,000) = 1591.5 Φ = MMF / S = 1600 / 5969 = 0

The MMF is given by:

The magnetic flux is given by:

S = S_core + S_air
