I recently posted a related question but this question seems to be requiring its own thread. There are available closed loop Hall IC current sensors which detects currents passing through conductors. My question is, if the conductor is replaced by a stable electro magnet and if we moved it, will the sensor show accurate changes/movements of the electromagnet if it's set-up in the closed loop system with no effect from external magnets or will it show any changes at all?

Here is a reference article regarding Hall IC current sensors.

Here is the previous thread where I have specified my exact application, however my main point here is Hall IC current sensors as I'm now more interested in them and other things I see that I can achieve with this.
