VELOCITY-FIELDS INSIDE A CONDUCTING SPHERE NEAR A SLOWLY MOVING CHARGE

Explicit expressions for first-order electric and magnetic fields created inside a conducting sphere by a nearby slowly moving charge are given. They are found to be independent of the sphere radius. On the contrary, outer first-order fields, which are also computed, depend on it. The energy dissipation by Joule effect is calculated and shown to agree with the external first-order work done on the charge to maintain its uniform motion.
