    The Magnetic Field Consider two parallel straight wires in which current is flowing. The wires are neutral and ... (pointing into the page). ... In terms of a, d, B, and q, find the momentum of the particle. In order to produce the observed deflection, the force on q at the entrance of the field region must be directed upwards (see Figure 5.1). ...
