Abstract: A transducer comprising an electrical conductor located in the field of a permanent magnet or an electromagnet, whereby, by passing a current through the conductor, force will be caused to act between the conductor and the magnet, the transducer including a further electrical conductor connected in a circuit with the first-mentioned conductor so as to carry a current related to the current through the first-mentioned conductor and such as to tend to nullify the effect of that current to alter the field of the magnet linking the first-mentioned conductor. A transducer element is also claimed.
