Embodiments of the present invention relate to magnetic gears comprising first and second moveable members arranged to interact in a magnetically geared manner via a first electrical winding arrangement arranged to generate, at least in part, a first magnetic flux having a first number of pole-pairs, and one or more pole-pieces arranged to modulate the first magnetic flux to interact with a second magnetic flux having a second number of pole-pairs, wherein the first number of pole-pairs is less than the second number of pole-pairs.
