RADIATION DUE TO THE RADIAL MOTION OF A CON DUCTING SPHERE IN A MAGNETIC FIELD,

Abstract

The electromagnetic fields resulting from the radial motion of a perfectly conducting sphere in a uniform magnetic field are studied. Expres sions or the radiated power are obtained for the cases of a sphere expanding or contracting at a uniform rate, for a sphere oscillating between two radii at a uniform speed, and for a sphere undergoing small amplitude oscillations. The effects of finite amplitudes are examined. These problems have applications in the study of the expansion of a plasma cloud in a magnetic field. (Author)
