The currents in the wires are in opposite directions.
- Two long parallel wires separated by a distance 'r' having current and have force per unit length which is given by .....(1) where is permittivity of free space whose value is .
If the current flowing through the wire are in same direction then they the wire attract each other and if the current flowing through the wire are opposite in direction then they the wire repel each other .
As it is given that two wires repel each other which means that current in the wires are in opposite direction .
Hence current flowing through wires are opposite in direction.
