Replacing Hall Effect Sensors with TMR Sensors - How and Why

Hi, what about if you want to detect non permanent magnets such as flexible sheets. They are usually magnetized linearly with North, South, North, South poles etc.. close to each other. They are inhomogenous so not permanent like a normal homogenous magnet which is easy to detect. If I want detection anywhere on the sheet do I need to put 3 tmr sensors in triangle form to be able to detect fields regardless of orientation or position of the sensors pcb above the magnetic sheet and this way at least one sensor will always detect one of the fields and give an output?
