Two insulated wires, each 2.90 m long,are taped together to form a two-wire unit that is 2.90 m long. One wire carries a current of 7.00 A;the other carries a smaller current I in the opposite direction. The two wire unit is placed at angle of 51.0° relative toa magnetic field whose magnitude is 0.360 T. The magnitude of the net magnetic force experienced by the two-wire unit is 3.13 N. What is the current I?
