How Do You Calculate Inductance Per Unit Length for Parallel Planar Conductors?

inductance of a capacitor-urgent

Hi,
Please can someone help me quickly with this problem:

Use both the flux and energy methods to calculate the inductance per unit length of a pair of parallel, planar conductors of length l , width w, and spacing d . Assume l >> w>> d and neglect fringing.

the fact that I don't have a current to work with confuses me.

Thank you
B

The inductance of a system is given by the ratio of the magnetic flux linked and the current. For any current I calculate the flux and find the ratio. I will be canceled out.
