Magnetic Circuits Problems And Solutions Pdf [2025]

Assuming μr = 1000, we get:

The MMF is given by:

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:

S_air = lg / (μ₀ * A) = 0.0005 / (4π x 10^(-7) x 0.02) = 1989 A/Wb Assuming μr = 1000, we get: The MMF

The magnetic flux is given by:

μr = l / (μ₀ * A * S) = 1 / (4π x 10^(-7) x 0.05 x 10,000) = 1591.5 The reluctance of the magnetic circuit is given

S = 0.5 / (4π x 10^(-7) x 1000 x 0.01) = 3980 A/Wb
