Abstract
An apparatus is for heating hydrocarbon resources in a subterranean formation having a wellbore therein. The apparatus includes an RF source, and a magnetic field radiator including a ferromagnetic body having an aboveground portion and a belowground portion coupled thereto. The magnetic field radiator includes a conductive wire coil surrounding the aboveground portion and coupled to the RF source so that an RF current through the conductive wire coil magnetizes the ferromagnetic body and generates a magnetic field from the belowground portion to heat the hydrocarbon resources.
