Adhesions can also form between loops of the small and large intestine. Adhesions form when inflammation occurs on the surface of the abdominal organs or the peritoneal lining of the abdominal cavity; the formation of scar tissue is a normal part of healing when there is inflammation.
Just as an electric charge is surrounded by an electric field, a moving electric charge is also surrounded by a magnetic field. Charges in motion have associated with them both an electric and a magnetic field. 23. 36.3 The Nature of a Magnetic Field. Electrons in Motion; Where is the motion of electric charges in a common bar magnet?
External work required to move charge. As you correctly note, the electric field will be perpendicular to the line AB and will not do any work on the test charge if it moves along that path. But, there must be some constraint to keep it on that path.
