The general form for the inductance of a solenoid (a long, straight coil of wire) is L = HN²A/₁ where u is the magnetic permeability of the environment, N is the number of turns, A is the cross-section of the coil, and I is the length. Consider two inductor coils with N₁ = 200 turns and N₂ = 400 turns, wound around the same basic form so that they have the same length and cross- sectional area. The first coil is L₁ = 100μH, and they are arranged so that the coupling coefficient is 0.5. Assume they are surrounded by air (a linear magnetic medium), and Hair = 4π x 10-7. Find L2 and Lm. 2.
