An actuator arrangement for use in a fuel injector of an internal combustion engine includes an inner core ( 30 ) comprising a plurality of laminates ( 30 a) and a first outer pole ( 32 ) for receiving at least a part of the inner core ( 30 ), wherein the inner core ( 30 ) and the outer pole ( 32 ) together define a first volume ( 46 ) for receiving a first electromagnetic winding. An injector is provided in which the actuator arrangement controls a valve arrangement, either a spill valve or a nozzle control valve, or both, so as to control injection by the injector.
