Abstract: An electromagnetic induction device including a magnetic core having a limb which has a first end and a second end, windings arranged around the limb, and a housing including magnetic material, which housing defines a space in which the magnetic core and the windings are arranged, wherein the housing defines a return path for the primary magnetic flux, enabling primary magnetic flux from the first end of the limb to flow via the housing to the second end of the limb.
