Two long, straight wires are parallel and 26 cm apart. (a) If each wire carries a current of 69 A in the same direction, what is the magnitude of the magnetic force per meter (in N/m) exerted on each wire? N/m (b) Does the force pull the wires together or push them apart? The wires are pulled together. The wires are pushed apart. The magnetic force per meter is zero. (c) What happens if the currents flow in opposite directions? O The wires are pulled together. O The wires are pushed apart. O The magnetic force per meter is zero. Additional Materials Reading
