The electrodynamic inverse problem of a conductivity determination for a metal sample from a measured resulting field outside of it and a known indirect field is considered. The solution ambiguity of an appropriate operator equation for magnetic and non-magnetic metals is established. For the case of non-magnetic materials the kernel of the integro-differential operator, included in the equation, is found.
