Self-Inductance of Two Parallel Wires

The self­inductance of two parallel wires is a property that describes the electromotive force caused by the change in current in the wires.

The self\[Hyphen]inductance increases linearly with the length of the wires and logarithmically with the ratio of the distance between the wires and the radius of the wires.

Formula

QuantityVariable["L", "MagneticInductance"] == Log[QuantityVariable["d", "Distance"]/QuantityVariable["r", "Radius"]]*Quantity[Pi^(-1), "MagneticConstant"]*QuantityVariable["l", "Length"]
