Question:

The figure shows two parallel, straight wires that are very long. The wires are separated by a distance of 0.065 m and carry currents of I1 = 15 A and I2 = 7.0 A. Find the magnitude and direction of the force that the magnetic field of wire 1 applies to a 1.5-m section of wire 2 when the currents have
(a) Opposite and
(b) The same directions.
