Electron Orbit at the Null Point (DC sputter coating)
This situation pertains to 'thin film sputter coating.'
Suppose I have some magnets in between a high voltage anode and cathode in a suitable vacuum. I understand that the electrons get trapped in the ...

Electrons, magnetism and electromagnetic waves
I know that moving charge (such as electrons moving around nuclei) produces a magnetic field. I also know that moving charge (again, such as electrons in atoms) can produce electromagnetic waves, ...

What direction is current for an electron in both $E$ and $B$ fields?
According to Fleming's left hand rule:
I am a bit confused however in the case of an electron travelling in a region of both electric and magnetic fields, which direction would the electric current ...

Why ray goes down when applied a magnetic force between it in the JJ Thompson experiment?
I have a question! I was learning about JJ Thomson's Cathode Ray Tube experiment and I understand why the ray goes up when it passes through a Wien's filter, but I cannot plenty understand why it goes ...

Can every mass obey the Newton's 3rd law?
As in, if we were able to produce a very huge amount of force on a very small body, would it push back with the same force? Given it doesn't break or disintegrate.
Like if we electromagnetically put ...

Electric/Magnetic Particles
I am given to understand these two things:
Electrons are "the result of", "the cause of", and "the" excitation in the electron field. (Sorry, couldn't come up with a more succinct way to sum up all ...

Is there scientific work about the inner structure of the electron and its magnetic and electric fields?
Since the electron posseses permanently an electric and a magnetic field to search for a model of the constituents of this inner structure and the two fields should be good scientific area of research....
