Thanks that is helpful. I had been trying to visualise what is happening and not having much success - I can imagine splitting the magnetic vector into 3 components and then measuring the rate of change of each of these particular components in the three directions. I did not realize you can use...

I am trying to understand the magnetic gradient tensor which has nine components. There are three magnetic field components, but there are also three baselines. These nine gradients are organised into a 3x3 matrix. I have read that only 5 of these terms are independent. What exactly does this...

No new findings. I think it has to do with symmetry but can't visualise it.
