Abstract
Coils for receiving or transmitting electromagnetic signals comprising a plurality of concurrently wound and fully or partially interpenetrating windings for which the resonance frequency can be varied over a broad range. The presently described embodiments provide for electromagnetic pickups for stringed musical instruments; however, it is appreciated that other embodiments providing for a wide variety of devices comprising pickup coil sensors are apparent. It is also apparent that a wide variety of devices are possible in which coils with concurrently wound and interpenetrating windings will serve as transmitting coils.
