MMF = NI = 500 x 10 = 5000 A-turns

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
