Formula: Inductance of Two Current-Carrying Wires
Opposite current carrying wires

Inductance

Unit
Inductance of two current-carrying wires whose currents flow in opposite directions. The wires are inductively coupled.

Distance

Unit
Distance between the two wires.

Length

Unit
Length of one conductor. The two conductors have the same length.

Radius

Unit
Radius of a cylindrical wire.

Vacuum permeability

Unit
Magnetic field constant is a physical constant and occurs whenever magnetic fields are involved. It has the value:\[ \mu_0 ~=~ 1.256 \cdot 10^{-6} \, \frac{ \text{N} }{ \text{A}^2 } \]
