Abstract
An electro-magnetic acoustic transducer (EMAT) system and method for controlling the EMAT system are provided. The system includes an electromagnet array with one or more electromagnets. Each electromagnet includes a magnetic core and a wound coil wrapped around the magnetic core. The electromagnet array generates bias magnetic fields having different patterns when the wound coils are energized differently.
