A wire of indefinite length crossed by a current ₁ = 0.5 A is placed at a distance r = 50 cm from a second undefined thread pa rallel to it. What current must flow in the second wire and in what direction, so that the force per unit of length between the two wires is r epulsive, and has an intensity equal to 1 N/m? O 5 A, in the same direction as /₁ 5 A, in direction opposite to ₁ O 10 A. in opposite direction to /1 O 10 A, in the same direction as/₁
