Detect 11 nanoamperes? No sweat. Old Keithley Picoammeters are still
very common. They measure coulombs also. SQUIDs even go much lower.
There is a good experiment in what you post. Maybe you could do the
experiment and post your results.

No, he said it's hard to detect the magnetic field generated by 11 nA
