    Re: Current sweep. Current changing linearly.

    Hi,

    Already written:
    One problem is, that you now mix two problems:
    1) how to build a current control circuit
    2) generate a precise control voltage (wich is not your initial question) for the current control circuit. This - with a dynamic and precision of 1:1000 - can be done with a good voltage reference and at least a 10 bit DAC.

    Re: Current sweep. Current changing linearly.

    1 µA in a loop of 0.1 m radius gives only 6 pT. No problem to generate nT with reasonable current parameters, I think.
