Speed of light

[illuusio]

Well, how about speed of light in strong gravitation field, like in black hole. Speed of light can be stopped.

[swansont]

Because your ammeter is also measuring all the internal fields that are cancelling each other out and is not sensitive enough to differentiate between just the outer electrons.

And yet if a field of the same strength were produced by a current, we could measure the current.

I made more serious thinking about speed of light. Certainly gravitation effects lights wave length, that's common knowledge. When it's said that even light can't escape from black hole, I don't think that's a whole truth. Maybe wave lenght is lost but photon particle itself keeps on moving at speed of light. Wave length can be imagened as photons rotation energy. Without that energy, photon impact on electron does practicly nothing because of too small kinetic energy.

 

Speed of light certainly is dependant on matter travelled through. But measured speed of light on Earth in vacuum is same as in "empty" space.

A single electron's quantum mechanical spin will produce a magnetic dipole moment, yet it cannot be argued that the electron is actually spinning since it is treated as a point particle and it does not return to its original orientation after a 360 deg rotation ( actually need 720 deg ).

 

So, where's the current ???

Magnetic moment

 

Main article: neutron magnetic moment Even though the neutron is a neutral particle, the magnetic moment of a neutron is not zero because it is a composite particle containing three charged quarks.

 

 

Electric dipole moment

 

Main article: Neutron electric dipole moment The Standard Model of particle physics predicts a tiny separation of positive and negative charge within the neutron leading to a permanent electric dipole moment.^[21] The predicted value is, however, well below the current sensitivity of experiments. From several unsolved puzzles in particle physics, it is clear that the Standard Model is not the final and full description of all particles and their interactions. New theories going beyond the Standard Model generally lead to much larger predictions for the electric dipole moment of the neutron. Currently, there are at least four experiments trying to measure for the first time a finite neutron electric dipole moment.

 

 

 

Your own books tell you the experiments are not sensitive enough, so why do you keep asking why we can't detect it????? A charge rotating with respect to another charge constitutes current. Even stationary charges produce electric fields, but ONLY moving charges produce both electric and magnetic fields.

Electric dipole moment ≠ current

 

Grasping at random quotes doesn't bolster your argument when the context of those quotes is not on the topic under discussion.

Every orbiting electron creates magnetic field. Only when orbits are lined up in material crystal (magnetized), effect is useful. Current is electron's movement from atom to atom.
