Right, or we can just link to the physical law itself: - Lorentz force - the force on a current carrying wire. No need for a long wire. It's in the range of micro-Newtons for few A…

The torsion balance introduces fixed biases, and can be operated only in XY plane. So in theory you're right, in practice it's not possible. Not canceling earth's magnetic field (a…

Approximately the same distance as a good microphone can pick up the audio anyway. Read about near-field vs far-field: https://en.wikipedia.org/wiki/Near_and_far_field

Not this shit again... Look closely at the picture of the test chamber in the article. Do you see Helmholtz coils surrounding the entire apparatus? Nope. https://en.wikipedia.org/w…
