A system for determining a stuck point of a pipe positioned within a wellbore includes a tubular housing and a sensor array positioned within the tubular housing. The system also includes ferromagnetic flux collectors and flux concentrators on either side of the sensor array. The flux collectors collect a magnetic flux that has been written to a portion of pipe. The flux concentrators intensify the flux to improve measurements of the flux that are acquired by the sensor array.

Magnetic freepoint indicator tool

A system for determining a stuck point of a pipe positioned within a wellbore includes a tubular housing and a sensor array positioned within the tubular housing, the sensor array arranged at a first end. The system also includes a first magnetic source positioned within the tubular housing, the first magnetic source arranged at a second end. The system further includes a second magnetic source positioned within the tubular housing, the second magnetic source arranged between the sensor array and the second end. The first magnetic source and the second magnetic source have a different magnetic field source.
