I have done an experiment named parallel action experiment, which shows the movement of a test coil in a magnetic field that is not allowed by Lorentz force law. Please see the video

The setup of this experiment is shown in Figure 1. The test coil carries a current that is influenced by the magnetic field B created by the magnet. The test coil, which is plane and perpendicular to its axle of rotation, can turn only in its plane. The video shows, when the current flows, signaled by the blinking of the led, the coil rotates in its plane.

Does Lorentz force exert a force parallel to the current? NO. However, this experiment shows that, YES, it does exist a force parallel to the current. This experiment makes a plane coil turn in the magnetic field of a magnet. The axle crosses the plane of the coil perpendicularly in the center. Only force parallel to the current can make it turn.

First photography: Will this coil turn?
Second photography: The coil and the magnet.
Third photography: The led will turn on when current flows in the coil. The referential system of the setup.

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.

Light is an electromagnetic wave whose total energy is the photon’s energy e multiplied by the number of photons n. This leads to constancy of energy inside a cone centered at the source (see Figure 1). So, whatever the distance from the source, a segment of the cone of unit length contains the same quantity of energy. For an electromagnetic wave, if we know the electromagnetic field, we can also calculate its energy in terms of electric and magnetic fields. This is the case for solutions of the electromagnetic wave equation. Contrary to light, these fields give a variable energy that become infinity near the source, violating physical principles.

EM wave transports energy in space, which is contained in electromagnetic field. The intensity and velocity of wave are computed with the wave equation, which will be used to derive the energy flux of wave. The flux of energy is the quantity of energy carried by a wave that crosses a surface. Energy flux must respect the energy conservation law. However, this is not the case for our EM wave equation as shown in the following.

Lorentz perpendicular action experiment

I have proposed an experiment design Lorentz torque to get precise data of magnetic force to compare with predictions by the two laws. Now, I propose a simpler but more impressive experiment which is a visual demonstration of the inconsistency of the Lorentz force law and whose result can be shown by video. Figure 1 shows the setup. A small rectangular coil abcd, called the test coil, is placed at the center of a long rectangular coil ABCD, called the inducing coil. The test coil is free to turn about its long axle. The current I in ABCD induces a magnetic field B which exerts a Lorentz force on the current i of the test coil and makes it tilt.

A charged insulator disc is under induction. Will there be a torque on its center? Perhaps one could use Faraday’s law to compute the torque. But is Faraday’s law valid for this application? Nevertheless, let us compute with Faraday’s law.
