Hello,

So, I need to get the resistance of this sensor show in the image bellow. It's a multilayer structure of different materials. What type of simulation do I have to do? And whats steps do I have to take?
After obtaining the resistance value I'll create a magnetic field to see the decrease in resistance due to materials properties. Fyi just started with maxwell.

In order to answer your question, we need more information: What is the excitation, AC or DC? How does the excitation apply on this sensor?

I'm simulating a walk-through metal detector, as in the image bellow. I need to detect the values of the magnetic field when there's a metal going through the portal and when there is nothing passing through it. There is a coil that generates a primary field, and the sensor is a Giant Magneto Resistance Sensor, that changes the resistance with different magnetic fields. So far I wasn't able to even find the passive resistance of the sensor without a field. Can someone help?
