Two straight wires positioned at right angles to each other (one in the horizontal plane and the other in the vertical plane) each carry a current of 15 A and separated by a distance of 20.0 cm. What should be the direction of current in each wire so that net force on each wire is ZERO?

Answer #1

When two wires are perpendicular to each other they don’t experience any magnetic force due to each other so whatever be the direction of current net force on the wires is zero.
