TOWARDS A PHYSICAL INTERPRETATION OF THE ANGULAR MOMENTUM PARAMETER ASSOCIATED WITH THE KERR METRIC

Abstract

The role of the parameter `$a$' associated with the Kerr metric which represents the angular momentum per unit mass of a rotating massive object has been converted into determining the rotationally induced quadrapole electric field outside a rotating massive object with external dipole magnetic field. A comparison of the result with that of the Newtonian case implies that the parameter `$a$' represents the angular momentum per unit mass of a rotating hollow object.
