It is known that when a current carrying conductor is placed within a magnetic field and current flows perpendicular to the magnetic field, a force is exerted on the conductor.
In figure 1, a square hollow conductor is shown in which current, I, is flowing perpendicular to the magnetic field, B. By Flemings left hand rule, the force acts downwards on the whole conductor. What happens when the same current carrying conductor is subject to a magnetic field generated within? In figure 2, the same hollow square conductor is wrapped with an energized coil and magnetic field is generated within its cross section. Current is made to flow through the conductor in the same way as figure 1. Would a perpendicular force be exerted on each of the four sides of the square cross-section? Could someone please explain this for me?
