PLEASE OBSERVE THIS IS ONLY A DRAFT intended to give the NPA members an opportunity to already now begin studying the issues prior to the NPA conference of next year (2010). New updated versions will continuously appear on this site appear. Small corrections must inevitably be made (Today: 25 Sep. 2009)

In this paper it is described how the Ampere Force Law can be applied to Ampere's Bridge. A detailed derivation based upon a paper by Wesley is being done. The results are questioned by Jonson, who promotes a usage of Coulomb's law. However, both proposals can account for forces of the order measured by Pappas and Moyssides in the early 1980s. It is up to the reader ro choose model. Finally, the law usually being used in order to predict forces between electric currents, the so-called Lorentz force, fails completely to predict the properties of the force.

The paper is mainly based upon a 20 years old paper by the author, published in the Chinese Journal of Physics 1997 (VOL. 35, No. 2, April, pp 139-149).

What is new is that the detaliled calculations (even updated) are presented, which is intended to make a check easier for anybody interested. It appeared to med that every step required rather lot of time before being successful.
