A 1.95 m long solenoid exerting Aharonov–Bohm force on a coil

This experiment shows the magnetic force on a coil exerted by the magnetic field of a long solenoid (1.95 m, 6.4 foot) that should be zero.

Disc magnet parallel action experiment

The magnetic field of the earth can rotate a flat coil in its plane. This is explained in Earth’s magnetic field and parallel action. Will a disc magnet rotate a flat coil the same way? The magnetic field of a disc magnet is central symmetric and the field lines are contained in median planes (See Figure 1). If a flat coil is coplanar with a median plane, the Lorentz forces on the currents will be perpendicular to the plane of the coil. So, Lorentz force could not rotate the flat coil in its plane. But in my experiment the coil rotates.

Earth’s magnetic field and parallel action

Earth’s magnetic field and parallel action

The magnetic field of the earth is uniform on its surface. The resultant Lorentz force a uniform magnetic field exerts on a coil of any shape is zero. The torque perpendicular to a flat coil is also zero. So, a current carrying coil in the magnetic field of the earth should stay immobile. However, my experiment shows that the test coil rotates in its plane. See the video of this experiment: http://youtu.be/JKMG8jY1RRg

Solenoid parallel action experiment

In “Q: Parallel action with a solenoid” I have asked a question: the magnetic field of a long solenoid being zero, will it make a coil rotate in its plan? This experiment will investigate the parallel action of a long solenoid. I have done this experiment and here is my result.

Q: Parallel action with a solenoid

According to my corrected magnetic force law, parallel currents attract each other and anti-parallel currents repel each other, see Theory about parallel action experiment. So, for the rectangular coil near the solenoid in Figure 1, the upper current is parallel to that in the front side of the solenoid and the lower current is anti-parallel. So, there would be a torque created on the coil and the coil should rotate.

However, the magnetic field outside a solenoid is zero and cannot act any force on a current. Moreover, there cannot be force parallel to current for classical theory.

So, If I do this experiment, will the coil rotate or not?

Aharonov–Bohm effect in CRT experiment

Nearly two years ago I proposed a CRT experiment to test the magnetic field of a solenoid, see Non-Lorentzian Magnetic force and Aharonov-Bohm effect in CRT, Blogspot, Word published June-27-2013. Since its consequence is great (see Consequences of macroscopic Aharonov-Bohm effect, Blogspot, word), I thought glory-searching physicists would rush on this simple experiment. But until now no one has dared to take the trophy and I have finally decided to carry it out myself. The result is as I predicted.

Non-loop induced voltage problem

The Induced conductor net problem could be solved if we can determine the induced voltage in part of the circuit. But is it possible that a voltage exist in no-loop wire? Let us see what the induced voltage is in a circular loop formed with 4 segments separated by resistors

Induced conductor net problem

My article Coil and resistor induction paradox shows that the potential energy of electrons in an induced coil is not correctly described by Faraday’s law. This is illustrated by Figure 1 in which a circular circuit with a resistor A is induced in a magnetic field; the resistance of the wire P is negligible. The inconsistency is that the electric field in the conductor wire P is zero and the moving electrons cannot collect energy. The present article exposes another problem: finding the potential in induced circuit with multiple resistor and branches.

Coil and resistor induction paradox

In my article Faraday’s Law Paradox, I have explained that in a magnetically induced coil the line integral of electric field is paradoxically zero in contraction with Faraday’s law. This paradox has aroused a long discussion which also reveals that the air gap between the coil’s terminals confused the understanding of the paradox. The closed coil below makes this paradox sharper. I will give my solution to this paradox.

Magnetism and dark matter

In my research on electromagnetism, I have understood that magnetism is forces created by moving charges and felt by moving charges. An electric current is a model of continuous flow of uncountable electrons moving in the same direction. This scheme seems benign but when I applied it to the Universe, I find in it a surprisingly judicious approach to solve the mystery of dark matter.
