Two parallel wires are separated by 0.25 m. Wire A carries 4.1 A and Wire B carries 10 A, both currents in the same direction. The magnetic permeability in empty space 0 = 4p 10-7 Tm/A. The magnitude of the force on 1.4 m of Wire A is:
a. 2.6 105 N.
c. less than 1.0 105 N.
b. 4.6 105 N.
d. 3.2 105 N.
