Systems and methods for detecting corrosion in pipes are disclosed herein. In one embodiment, an apparatus for detecting corrosion in an object includes an electromagnetic acoustic transducer (EMAT) having a ferromagnetic core and a plurality of permanent magnets arranged peripherally around the ferromagnetic core. The permanent magnets are arranged to produce a magnetic field through the ferromagnetic core. The apparatus also includes a coil between the ferromagnetic core and the object.

Electromagnetic acoustic transducer (EMAT) for corrosion mapping

Systems and methods for inspection of pipelines are disclosed herein. In one embodiment, an electromagnetic acoustic transducer (EMAT) transceiver (TRX) for inspecting a pipe includes a multichannel EMAT transmitter (TX) having multiple collocated transmitter coils. The EMAT TX can generate forward-propagating ultrasound waves and backward-propagating ultrasound waves. The forward-propagating ultrasound waves have higher amplitude than the backward-propagating ultrasound waves. The EMAT TRX also includes a multichannel EMAT receiver (RX) having multiple receiver coils that can receive the ultrasound waves transmitted by the EMAT TX through the pipe.

Methods and devices for inspection of pipelines

Systems and methods for non-destructive testing of specimens are disclosed herein. In one embodiment, an electromagnetic acoustic transducer (EMAT) includes an electro-permanent magnet (EPM) configured to controllably apply a biasing magnetic flux to a target location. The EPM includes a hard magnet, and a soft magnet at least partially enclosing the hard magnet. The EPM also includes a magnetizing coil having a plurality of turns at least partially encircling the soft magnet. The magnetizing coil is configured to controllably magnetically bias the soft magnet when a current is applied to the magnetizing coil.

Combined electromagnetic acoustic transducer (EMAT) and electro permanent magnets (EPMS) for bias field control

The systems, apparatus, and methods disclosed herein provide access to systems located within a closed structure, such that the systems are traditionally difficult for humans to access. Exemplary structures include an engine compartment, airplane wing, or fuselage. This access allows a system located within the structure to be electrically coupled with an electrical I/O device located outside the structure. Access to a system located within the closed structure is provided by way of a hole.
