Two wires are separated by a distance d. They both have a current I a) What is the force on wire 1) due to wire 2) if the currents are in the same direction? What is the direction of the B-field between them? b) What is the force on wire 1) due to wire 2) if the currents are in opposite directions? What is the direction of the B-field between them? c) Do either of these quantities change if I rotate the wires in the xy-plane?
