Consider two parallel wires carrying current in the same direction. Which one of the following statements is true concerning this situation? O The two wires will repel each other, even no external magnetic field is applied to the wires. O The two wires will repel each other, only if an external magnetic field is applied to the wires. O The two wires will attract each other, even if no external magnetic field is applied to the wires. O The two wires will attract each other, only if an external magnetic field is applied to the wires. The wires will be neither attracted nor repelled from each other regardless of whether or not an external magnetic field is applied to the wires.
