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?
Magnetic Field Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits. The magnetic field B is defined in terms of force on moving charge in the Lorentz force law. The interaction of magnetic field with charge leads to many practical applications. Magnetic field sources are essentially dipolar in nature, having a north and south magnetic pole. The SI unit for magnetic field is the Tesla, which can be seen from the magnetic part of the Lorentz force law F magnetic = qvB to be composed of (Newton x second)/(Coulomb x meter).
