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?
An electric current flowing in a wire creates a magnetic field around the wire, due to Ampere's law (see drawing below). To concentrate the magnetic field, in an electromagnet the wire is wound into a coil with many turns of wire lying side by side.he magnetic field of electromagnets in the general case is given by Ampere's Law : which says that the integral of the magnetizing field H around any closed loop of the field is equal to the sum of the current flowing through the loop.
