An electromagnetic actuator (300) includes a first and second magnetic members (310,320) that are displaceable relative to each other and are arranged to provide a magnetic circuit; and a coil (340.1, 340.2) configured to, in use, receive a current to generate a magnetic flux through the magnetic circuit, thereby generating a force between the first and second magnetic members in a first direction (Y), the magnetic flux, in use, being transferred between the first and second magnetic members through a first surface (312) of the first magnetic member and a second surface (322) of the second magnetic member, the first and second surface being separated by an airgap (390), wherein the first surface and the second surface are arranged relative to each other such that an outer dimension (L1) of the first surface extends beyond an outer dimension (L2) of the second surface in a second direction substantially perpendicular to the first direction. |
