Problem

An infinitely long straight wire carries a current of 15 A vertically upward. A 0.25 m long conductor is situated 6 cm north of the wire and is oriented horizontally along the east–west line. The conductor carries a current of 4 A towards the east. Find the magnitude of the force acting on the conductor. (a) 2.5×10−5 N2.5\times10^{-5}\,\text{N} (b) 0 N0\,\text{N} (c) 5.0×10−5 N5.0\times10^{-5}\,\text{N} (d) 1.0×10−4 N1.0\times10^{-4}\,\text{N}
