Awire is oriented along the x axis. it is connected to two batteries, and a conventional current of 1.9 a runs through the wire in the +x direction. along 0.26 m of the length of the wire there is a magnetic field of 0.56 t in the +y direction, due to a large magnet nearby. at other locations in the circuit, the magnetic field due to external sources is negligible. what are the direction and magnitude of the magnetic force on the wire?
