- The figure below is a cross-section of the solenoid in the plane containing its axis. Make a
sea-of-arrows sketch of the magnetic field in this plane. The length of each arrow should at least
approximately reflect the strength of the magnetic field at that point.
Does the field seem to have sources or sinks?- What do you think would happen to your sketch if you reversed the wires?
