Rearranging and solving for μr, we get:
S = 3980 + 1989 = 5969 A/Wb
The magnetic flux is given by:
A magnetic circuit has a coil of 500 turns, a core with a cross-sectional area of 0.05 m², and a length of 1 m. If the current through the coil is 10 A and the magnetic flux is 0.5 Wb, find the relative permeability of the core. magnetic circuits problems and solutions pdf
Φ = MMF / S = 1600 / 5969 = 0.268 Wb
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. Rearranging and solving for μr, we get: S
MMF = NI = 100 x 5 = 500 A-turns
