Question
In earlier times when many households received nondigital
television signals from an antenna, the lead-in wires from
the antenna were often constructed in the form of two paral-
lel wires (Fig. P31.50). The two wires carry currents of equal
magnitude in opposite directions. The center-to-center
separation of the wires is w, and a is their radius. Assume
w is large enough compared with a that the wires carry the
current uniformly distributed over their surfaces and negli-
gible magnetic field exists inside the wires. (a) Why does this
configuration of conductors have an inductance? (b) What
TV antenna

constitutes the flux loop for this configuration? (c) Show
that the inductance of a length x of this type of lead-in is
