A current in a wire generates a magnetic field around the wire in a direction determined by the appropriate version of the right hand rule. If you wind the wire into a loop, and stack many loops, the vector field adds in some places and not in others, assuming a specific shape. This is a coil, or solenoid. What is the primary feature of the magnetic field of a current in a coil. Describe how the field of the wire combines into this configuration. Be sure to clarify the right hand rule used.
