References for Experimental Validation Of Lorentz Force I am writing the paper that involves the history of Lorentz force and I would very much like to add some specific references that involve experimental validation of Lorentz force. The only one I was able to find was J.J. Thomson 1897 paper "Cathode Rays" published in "Philosophical Magazine". However, in that paper the Lorentz force is not mentioned although it is evident that the deflection of the electron beam must be due to the Lorentz force. Can someone please point me to historic papers that describe the experiments that validate the Lorentz force? 
 A: So I am personally interested in electromagnetic forces applied to condensed matter, and while these systems perhaps do not exhibit the simplest manifestations of Lorentz forces, I can recommend two historical papers:
Edwin Hall (1879): "On a New Action of the Magnet on Electric Currents"
This paper described the discovery of the Hall Effect, which of course is a manifestation of the Lorentz force. Its a great read just to see how they wrote scientific papers back then (rather informally), but it's also historically interesting to see the motivation for his experiment: It was controversial whether the "magnetic force" acts upon the electric current or conductor which carries it. Maxwell thought it was on the conductor, and Hall seemed to show it was on the current.
Nichols and Hull (1901): "A Preliminary Communication on the Pressure of Heat and Light Radiation"
This is one of the earliest papers on quantitative measurement of radiation pressure, which of course can be understood in terms of Lorentz forces (the magnetic force term is what applies the radiation pressure for normally-incident light on matter). See also Rothman and Boughn, American Journal of Physics 77, 122 (2009) (a more pedagogical take) for more on this.
