In Fig. 20–47, charged particles move in the vicinity of a
current-carrying wire. For each charged particle, the arrow
indicates the initial direction of motion of the particle, and
the + or – indicates the sign of the charge. For each of
the particles, indicate the
direction of the magnetic
force due to the mag-
netic field produced by
the wire. Explain.
