Re: [Phys-l] Ampere's original magnetic force law



A discussion of "Weber Electrodynamics" can be found at:

www.ias.ac.in/pramana/v55/p393/fulltext.pdf

If interested in the Ampere's law controversy, you will want to consume this.
We were not taught this (Weber's electrodynamic model) in the traditional E/M curricula.

Subject: [Phys-l] Ampere's original magnetic force law

I have been asked (by engineers at Penn State) to submit this topic to the List for comments:

http://www.df.lth.se/~snorkelf/LongitudinalMSc.pdf

It concerns a controversy regarding Ampere's original formulation of the basic magnetic force law between current elements.
Apparently he was persuaded to this version because it obeys N3 even in the strong form (equal and opposite "central" forces).
This is contrary to the traditional force law, which comes from the Biot Savart relation and the Lorentz QVxB force.

Examples of experimental evidence for the Ampere longitudinal force component are cited. Should these results be attributed to an other-than-magnetic component of the force between current elements?

Could the original Ampere magnetic force law possibly be reconciled with Maxwell's equations and the Lorentz force?

Your comments and analyses, please.
