Provided is a disclosure for a magnetic particle inspection system configured to generate a magnetic field for inspection of a part, comprising a programmable logic controller (PLC), a current source, and a current sensing device. The PLC may be configured to communicate an amperage signal, for amperage of an output current, to a current source, and communicate a first signal to the current source to output the output current. The current source may be configured to adjust the amperage for the output current based on the amperage signal, and output the output current upon receiving the first signal. The current sensing device may be configured to measure an output amperage of the output current, and communicate amperage information based on the output amperage to a signal conversion device. The PLC may, in response to feedback from the signal conversion device, update the amperage signal.
