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 Amps, for 10cm, at earth magnetic field:…
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 (an easy thing to do) when measuring…
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/wiki/Helmholtz_coil It's the same story…
It's probably by design, iPhones support magnetic-induction hearing aids, see here: https://support.apple.com/en-us/HT202186 The are 2 standards, the old "telecoil" (direct) and the new FM loop, both operating at low…
