The are hung from the same support bar by strings of length .080 m so that the wires run parallel to the ground. The current causes the wires to repel from each other, so they hang with an angle θ = 20◦ between the supporting strings of the two wires. Are the currents in the same or opposite directions? What is the magnitude of the current?

Two long, parallel, current-carrying wires lie in an xy-plane. The first wire lies on the line y = 0.400 m and carries a current of 25.0 A in the +x direction. The second wire lies along the x-axis. The wires exert attractive forces on each other, and the force per unit length on each wire is 290 μN/m.
