If current in two parallel wires flow in opposite directions, the force between the wires will:

Two free parallel wires carrying current in opposite direction :

When the currents flowing in two long straight conductors parallel to each other and separated by a finite distance are flowing in opposite directions. The force that exists between the conductors is

Two parallel wires 1 m apart carry currents of 1A and 3 A respectively in opposite directions. The force per unit length acting between two wires is:

In an experiment , setup A consists of two parallel wires which carry currents in opposite directions as shown in the figure. A second setup B is identical to setup 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.
