Sure, but using open wires you're probably leaving the reign of 
approximations where values such as inductance (and mutual
inductance) are making sense. The current density (which is
responsible for the magnetic field) is not just determined by
the current in the wire anymore, but also by the d/dt of the electric
field. That is, capacitive and inductive effects are not independent
of each other anymore.
