Two long wires are placed parallel to each other. Wire 1 is very long and wire 2 has length 10 cm. The wires are separated by a distance of 2 mm. Wire 1
carries a current of 100 mA and wire 2 carries a current of 250 mA. The currents are flowing in the same direction. Calculate the magnitude of the force
that wire 1 exerts on wire 2, and determine whether this force is attractive or repulsive. 40 = 4 x 10-7T-m/A
