Non-linearities appear only when one considers loop corrections in quantum electrodynamics, arxiv.org/abs/hep-th/0406216, or extensions of electromagnetism, arxiv.org/abs/hep-th/0309108. The quantum corrections are tiny, ~1% or less, and, for all practical intents and purposes, unseen. Certainly these non-linear effects are unmeasurable with a standard bar magnet interacting with Earth's magnetic field. | |

I think that this influence will also change the magnetic field of the bar magnet. The change might be very slight but it would change the field and the way that it would be measured. Even if the bar magnet is aligned with the magnetic field of the earth and there isn't any torque applied to the bar magnet the earth's magnetic field will still have an impact. | |
