Electromagnetic acoustic transducer with cross-talk elimination

An electromagnetic acoustic transducer useful for analyzing an object comprising:

• a core;
• an electrically conductive core winding circumscribing the core in selective communication with a current source;
• a magnetic field source, so that when the transducer is disposed proximate the object and pulsed current flows from the current source through the core winding in one direction the core is magnetized and with the magnetic field source produces a magnetic field that combined with a magnetic field from the magnetic field source to produce a resultant magnetic field in the object and when the current flows through the winding in an opposite direction a magnetic field is produced that cancels the magnetic field from the magnetic field source;
• an electrically conductive coil in electrical communication with a current supply of RF current, so that when the current supply supplies current acoustic waves are produced in the object.
