The magnetic field outside a solenoid is zero: the fields generated by each coiling on the diametrally opposed points of a spire cancel each other on the outside of the solenoid, causing the field to go to zero. Only at the terminations of the component can you observe a non-zero field on the outside of the coil.

Moving charges experience a force in a magnetic field. If these moving charges are in a wire—that is, if the wire is carrying a current—the wire should also experience a force. However, before we discuss the force exerted on a current by a magnetic field, we first examine the magnetic field generated by an electric current.
