The reluctance of the magnetic circuit is given by:
where S_core is the reluctance of the core and S_air is the reluctance of the air gap.
The reluctance of the air gap is given by: magnetic circuits problems and solutions pdf
Rearranging and solving for μr, we get:
Φ = MMF / S = 1600 / 5969 = 0.268 Wb
The reluctance is also given by:
The MMF is given by:
S = 3980 + 1989 = 5969 A/Wb
S = l / (μ₀ * μr * A)
MMF = NI = 200 x 8 = 1600 A-turns
The magnetomotive force (MMF) is given by: The reluctance of the magnetic circuit is given
