A question on perturbed flux function
Given a magnetic field $\mathbf{B}=B_{0}\left(\dfrac{xz}{z_{s}^{2}},\dfrac{yz}{z_{s}^{2}}, 1-2\left( \dfrac{x^{2}}{r_{s}^{2}}+\dfrac{y^{2}}{r_{s}^{2}}\right) -\dfrac{z^{2}}{z_{s}^{2}}\right)$ with the ...

Physical meaning of the multipolarity of gamma radiation
During my nuclear physics class, we talked about the multipolarity of gamma radiations but without going too much into the details, and I was wondering about the meaning of that, how can the radiation ...

If we use Negative Ions as probe for nuclear reactions, will they get deflected?
I am studying the basics of Nuclear Physics, and just read about the Rutherford experiment.
My question is if we use Negative Ions as probe for nuclear reactions, will they get deflected?
If yes then ...

How does a photon interact with EM field of a nucleus thus exchange momentum and recoil the nucleus when pair production happens? [duplicate]
The photon must be near a nucleus in order to satisfy conservation of momentum, as an electron–positron pair produced in free space cannot satisfy conservation of both energy and momentum.[4] Because ...

Does a moving atom with a nuclear magnetic moment generate an electric field?
I have read that moving ions generate a magnetic field as it moves.
Similarly, is this also true regarding the nuclear magnetic moments of the atom? In other words, would a moving atom with a nuclear ...

Are wide-range EMPs (that knock out electronics) possible? Or is that just in hollywood/fiction?
In movies like GoldenEye, they talk about how detonating a nuke in the sky will disrupt all electronics.
My question is: is disrupting all electronics in a significant area (the size of a small city) ...

Nature of force on electron in atom
what is the nature of force on electron in atom .Is it coulombic or electromagnetic force?
As electron is in random motion so we cannot take it as electrostatic force. Please clear my confusion.

Do forces get affected by relativity?
Do forces change their behavior due to the relativity?
For example if a charged particle deflects through an electric field, would the pattern and amount of deflection differ in speeds near speed of ...

Could somebody explain alpha channeling in tokamaks?
Could somebody explain alpha channeling in Tokamaks and mirror machines? Energetic alpha particles (in the center of the torus or mirror device) born in fusion reactions, interact with a wave and ...

Nuclear fusion reactors and neutrons
The majority of energy produced by nuclear fusion is harnessed by neutrons or protons that split out from the product.
Given the dominant fusion method today is Deuterium + Tritium which produces He ...

Are electric force and strong force equal in magnitude?
Should the electric force and the strong force be equal for a nuclei to be stable? Because if perhaps, the strong force is now more than that of the electric force, then shouldn't the nucleus collapse ...

How can positive energy fields negatively contribute to the mass?
Mass decreases in the presence of attractive forces according to the formula : $\delta m=\frac{E}{c^2}$, where $E$ is the energy of the binding field. My problem is that field energy is always ...

Why were sparks created in Rutherford's alpha particle scattering experiment?
So I just read that when alpha particle hit the gold foil sparks were created. And these flashes were used to determine the angle of scattering. So were the sparks created because the alpha particles (...

Would atoms be smaller or larger if the electromagnetic force was slightly weaker?
Some sites claim that atoms would be larger in size if the EM force was weaker, because the electrons would 'orbit', on average, farther from the nucleus....
Other physicists claim that atoms would, ...
