I have done an experiment that shows that magnetic force does not respect the Lorentz force law in the magnetic field of a narrow magnet. The video of this experiment is under this link:

In this article, I will explain the experimental result and the revealed flaw of the Lorentz force law.

Experimental torque

First, let us compare the theoretical prediction by the Lorentz force law with the experimental result. In Figure 1, the test coil is represented by the square coil carrying the current I placed in the magnetic field B. The experiment shows that, in the magnetic field of the magnet, the test coil turns about the x axis (part (a) in Figure 1), but not about the y axis (part (b) in Figure 1).

Dear readers and experimenters,

I have good news. After the fail of a first try of the Lorentz perpendicular action experiment, I have found the cause of the fail and modified the setup to get around it. This time I get a success. The video of this experiment is on Youtube under this link:

In this video, I have put
1) General photograph of the setup
2) General video of the test
3) Close-up video of the test coil’s movement
4) Photographs of the magnet and the test coil

Dear readers and experimenters,

I have a bad news: I have carried out the Lorentz perpendicular action experiment, blogspot http://pengkuanem.blogspot.com/2012/12/lorentz-perpendicular-action-experiment.html
academia http://www.academia.edu/2237784/Lorentz_perpendicular_action_experiment
. It seems that the magnetic force on the test coil in perpendicular position has apparently the same magnitude than in parallel position. This shows that there is an error in my calculation or in my theory. I think of the experimenters who may be doing this experiment and decide to announce immediately this news to inform them.

Firstly, I want to say sorry to them who have given me their trust. I also want to thanks the readers who have given their time to consider my theory. I preferred to announce this news by my self rather than by someone else who would carry it out and find negative result. I believe that honesty is essential in sciences.

I’m searching actively what is the error and will be back because, although this experiment failed, my paradoxes about the Lorentz force law still hold and this force cannot generate freely energy.

Thanks to you all.
