An inductive sensor on the basis of an annularly closed, soft-magnetic core (K) is disclosed wherein the current to be measured produces an inductive change within the annularly closed magnetic circuit, said inductive change being taken via a measurement winding (MW) wrapped around the core. In order to achieve a linear behavior within a broad range of measurement, the annularly closed core comprises core regions (KB) that comprise a magnetic composite powder material and, in particular, a ferrite polymer composite material (FPC).
