A wire carries a current of 10A in the +xdirection in a uniform magnetic field of .40T. Find the magnitude of the force per unit length and the direction of the force on the wire if the magnetic field points in the (a) the +x direction, (b) the +y direction, (c) the +z direction, (d) the -y direction, and (e) the -z direction, and (f) at the angle of 45 degrees above the +x axis and in the x-y plane.
