Coil Failure pt 13: Proximity Effect
April 5th, 2010
When the currents flow in opposite directions, a strong magnetic field forms in the area between the bus bars. This occurs because in this area the magnetic field lines produced by each bus bar have the same direction. Therefore, the resulting magnetic field between the bus bars will be strong. However, because the currents are concentrated in the internal areas, the external magnetic field will be weak. The external magnetic fields produced by both conductors will have opposite directions, and tend to cancel each other out. This phenomenon is used in co-axial cables.
