Abstract
An electromagnetic device, which includes a ferromagnetic flux guide; an insulated electrical conductor positioned adjacent to the ferromagnetic flux guide; and, an intermediate support structure positioned between the ferromagnetic flux guide and conductor which includes at least one resiliently deformable member arranged to allow relative movement between the ferromagnetic flux guide and the insulated electrical conductor, in which the relative movement is due to thermal expansion or contraction of the ferromagnetic flux guide and insulated electrical conductor.
