    Electromechanical Systems: Determine the voltage across a moving coil

    Homework Statement: Figure shows two mutually coupled coils, for which L11= L22 = 3 + 2/3x (mH) L12 = L21 = 1/3x (mH) where x is in meters, (a) If i1 = 5 A dc and i2 = 0, what is the mutual electrical force between the coils at x = 0.01 m? ( b ) If i1 = 5 A dc and the second coil is...
