Corrected law and Perpendicular action experiment

Link

In my Lorentz perpendicular action experiment, (see Lorentz perpendicular action experiment and Lorentz force law, blogspot academia) the movement of a test coil proved experimentally that the magnetic force on it does not verify the Lorentz force law and in consequence, showed a flaw of the law.

In this experiment, the magnetic field of a magnet exerts a force on the test coil and makes it turn (see Figure 1). According to the Lorentz force law, the test coil should turn about the axle whether it is parallel to x-axis or y-axis. But the experiment showed that it does not turn when the axle is parallel to y-axis.

In the following, I will explain the experimental result using the corrected law of magnetic force that I proposed in Correct differential magnetic force law, blogspot acdgemia, and show that this law describes well the movement of the test coil.

Lorentz perpendicular action experiment and Lorentz force law

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).

Success of the modified Lorentz perpendicular action experiment

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.

Energy density of electromagnetic wave

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.

Electromagnetic wave energy flux

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

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.

Faraday’s torque experiment

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.

Partial EMF measurement

Faraday’s law gives EMF as the voltage measured across the 2 terminals (A and D in Figure 1) of a loop under the induction of a varying magnetic field. Partial voltage between 2 intermediate points in the loop does exist, but is impossible to measure with a voltmeter. In Figure 1, a voltmeter connected to two arbitrary points B and C, will read the voltage induced by the magnetic field passing through the surface in grey. If the surface is reduced to zero, the voltmeter would read 0. This is why no study of partial voltage exists until now. I propose here an experiment to measure the partial voltage.

Can EMF distribution be known?

Can EMF distribution be known?
19 October 2012

EMF is the generated voltage in a loop under the induction of a varying magnetic field B. But the electric field of the EMF is non-conservative and one has no information about its distribution in space. The present study may give some hints for it.
