As we know Biot-Savart law follows right-hand rule, like this:
...so the question is why right-hand rule, why not left?
I suppose it must have something to do with electron's magnetic dipole moment or "spin", as that's the only source of asymmetry I am aware of in this scenario. It follows then the orientation of the spin axis could be what defines this magnetic rotational direction, which would imply then the spin axis orientation is defined by the velocity vector. But still, the question remains, how or why could velocity vector have any specific directional impact on either intrinsic electron spin axis orientation or Biot-Savart magnetic field rotation?
