Question: An infinitely long straight wire carries a current I = 1.0 A that flows in the positive direction. The external magnetic field at position

An infinitely long straight wire carries a current I = 1.0 A that flows in the positive direction. The external magnetic field at position x along the wire is given by B(x) = Boe||/ay where Bo = 110 mT and a = 0.15 m. What is the force F on the wire due to this external magnetic field?
