Imagine a ball with 10 cm of radius charged to 1 kV. It has a
capacitance of 11 pF and stores 11 nanocoulombs. If you move it at
1 meter per second, the magnetic field generated is equivalent to
what would be generated by a current of just 11 nanoamperes.
Difficult to detect.
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.
