In a long, straight, current- carrying wire, the electrons are moving to the west. If the wire is in a uniform magnetic field pointing upward, what is the direction of the force on the wire? Answer this from two different view-points: that of the force on the electrons, and then that of the force on the wire considering conventional current direction. Are your answers the same?
