Thanks a lot. That is very helpful. Are there other devices that can measure small magnetic fluxes and very small variations in them? I would like to measure small changes in a magnetic flux without having to measure the induced AC current resulting from this
variation, since such picoammeters...
Hello everyone. I am looking for a practical method to detect very small currents in nano or pico amperes. Are there galvanotmeters or devices capable of doing that? Thanks a lot.
