Circular magnetic Field measurement in tube

Dear NDT expert,

During MPI operation, I'll struggle with the measurement of remanent magnetic field in steel pipe. Usually, we only measure longitudinal magnetic field from the pipe face.

I'd like here to measure the remanent magnetic field in circumferential direction which is thus not exiting the pipe. The only way I see it is to machine a longitudinal notch and place my Hall-effect probe within (but it is damaging the pipe).

Do you have a solution ?

Thank you in advance !

Raphaël
