hi,
D3 is a 5.6V Zener
Ignore the Ip, 0.01, they are for simulation only.
Use a JFET CC, is a junction FET Constant Current sink
The .dc V2 etc...... is a simulation command, ignore it.

Alec-t asked if it would be possible to simply use a POT immediately after the COIL around the first Opamp, then set the range between the two different circuits (1mv-1 and 1-10) each time.
In this early question of yours, you ask if I want linear? I was wondering if there is a way of adding components that give a none linear line, as my black line on your Graph (attached).
This would be a luxury, failing this, I'm more than happy with your original design.
