In an experiment, set up $A$ consists of two parallel wires which carry currents in opposite directions as shown in the figure. $A$ second set up $B$ is identical to set up $A$, except that there is a metal plate between the wires. Let $F_A$ and $F_B$ be the magnitude of the force between the two wires in setup $A$ and setup $B$, respectively.

Metal plate between wires may modify field pattern within the metal volume but number of field lines is not changed.
So, force between wires is same in both cases and is non-zero.
i.e. $\quad F_A=F_B \neq 0$.
