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. What is the y-value (in m) of the line in the xy-plane where the total magnetic field is zero? .207 Use the right-hand rule to determine the possible location of a point where the magnetic field is zero. Write an expression for the force of attraction between the wires, find expressions for the magnetic fields due to each wire at the point, and set them equal. Use your expression for the force per unit length to eliminate one of the currents, and solve for the required distance. m
