Hello, I'm making a sensor for measuring changes in the electromagnetic field.

I constructed a model of the sensor, but don't know how to set up a simulation for measuring the resistance change in the sensor.

Someone can help me?

Hello Sidinei,

       We could measure flux density in the sensor in the field result, and then based on the flux density, to find the resistance manually.

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?
