Unformatted text preview: a steel or ferrite core. µN A The magnetic ﬂux within the coil is Φ = l i where N is the number of turns, A is the cross-sectional area of the coil and l is the length of the coil (around the toroid). µ is a property of the material that the core is made from and is called its permeability . For free space (or air): µ0 = 4π × 10−7 = 1.26 µH/m, for steel, µ ≈ 4000µ0 = 5 mH/m.
