A5 cm length of wire carries a current of 3 a in the positive z direction. the force on this wire due to a magnetic field vector is vector = (-0.2 ihatbold + 0.2 jhatbold) n. if this wire is rotated so that the current flows in the positive x direction, the force on the wire is vector = 0.2 khatbold n. find the magnetic field vector.
