    The acoustic wave passes the material boundary and creates dynamic electromagnetic fields in a conductive material exposed to a steady magnetic field, which then can be detected by a received EMAT. The inverse effect applies whereby the acoustic wave forces the charged particles to move with the aid of the magnetic field of permanent magnet bias.
