Abstract
A transducer is provided that converts energy between two forms using active components. The transducer also includes passive components in contact with the active components that perform passive component functions separate from the energy conversion function. The passive components have elastic properties that are modifiable by exposure of the passive component to a magnetic field to selectively control the energy conversion function.
