Claim:
1. An electromechanical actuator for generating a mechanical force to be transferred to a material being measured or processed, wherein variations in temperature to which the material is exposed during measurement or processing may cause errors in the measurement or processing, the electromechanical actuator comprising: an electromagnetic coil that generates heat as it is energized; a connecting member mechanically coupled between the electromagnetic coil and the material, the connecting member being configured to transfer the mechanical force from the electromagnetic coil to the material; and a magnet disposed between the electromagnetic coil and the material and disposed between the electromagnetic coil and the connecting member to thermally isolate the material and the connecting member from the heat generated by the electromagnetic coil, the magnet having a channel in which the electromagnetic coil is disposed, the channel having a channel opening that faces away from the material, the channel opening allowing heat generated by the electromagnetic coil to be directed away from the material, the magnet further having a central hole through which the connecting member extends.
