  Motion Control: Linear motion devices: What is a voice-coil …

  201872 · Another type of motion device, the solenoid, is sometimes confused with the voice-coil actuator. However, while a voice coil generates a force based on an interaction of a current carrying conductor in a permanent magnetic field, a solenoid generates force based on an electromagnetic field that is created by a current carrying conductor.
