Summary

WHEN A TRANSVERSE MAGNETIC FIELD IS APPLIED, THE DISTRIBUTION OF TRANSPORT CURRENT IS FORCED TO CONCENTRATE INTO THE INNER CIRCULAR CROSS SECTION REGION DURING A CHARACTERISTIC TIME CONSTANT CALLED THE COUPLING TIME CONSTANT. SECONDLY, THE CHARACTERISTIC TIME CONSTANT FOR THE TRANSPORT CURRENT DISTRIBUTION INSIDE THE INNER REGION TO APPROACH A UNIFORM DISTRIBUTION IS A NEW TIME CONSTANT CALLED THE < UNIFORMING TIME CONSTANT >, THOUGH THE VARIATION IN THE DISTRIBUTION DOES NOT OCCUR UNLESS THE EXTERNAL MAGNETIC FIELD CHANGES WITH TIME. THE MODEL OF THE CURRENT DISTRIBUTION EXHIBITS A REMARKABLE DIFFERENCE FROM THE EXISTING MODELS, ESPECIALLY FOR THE WIRES CONTAINING VERY FINE SUPERCONDUCTING FILAMENTS.
