Does electric and magnetic field from electromagnetic radiation are 2D based? [closed]
I'm getting into physics, specially in electromagnetism.
When we're talking about electromagnetic radiation. Does it has a 2D shape when it's propagating through space?
Does Maxwell's equations ...

ELF Electromagnetic wave propagation in plasma (ionosphere) - how?
Can an extremely low-frequency electromagnetic wave (below 500 Hz for example) propagate through an ionosphere? The cutoff frequency of Earth-ionosphere waveguide is approximately 1.7 kHz so I ...

How could I calculate the strength of an electromagnetic field sufficient enough to generate plasma in low pressure argon gas?
For context, I wish to create a plasma toroid in a glass sphere of 25 Torr Argon gas like in the photo below; there are multiple examples of how to do this online using a class E oscillator ...

Why In an electromagnetic wave both electric and magnetic waves are in sync and perpendeculare? if one makes the other shouldnt there be a delay? [closed]
Why are electric and magnetic waves in phase if one induces the other? Shouldn't there be a delay, similar to how potential energy converts to kinetic energy and vice versa? Additionally, why are ...

Magnetic Field on a point in a current carrying wire
Current carrying wire produces a magnetic field around it, we all know that.
A circular wire carrying current produces a magnetic field around it due to the flow of electric charge. This phenomenon is ...

Is $\vec E$ more effective than $\vec B$ and why?
While reading about the Poynting vector in Optics (5 ed) by Eugene Hecht, I found the following line in page 42, from chapter 3.
Since, as we have learned, $\vec E$ is considerably more effective at ...

Are all recursive interactions between electric and magnetic fields always orthogonal to each other?
ecursively, this implies that changes in the electric field generate the magnetic field, and vice versa, akin to the plane wave solution resulting from specific boundary conditions intentionally ...

Can light propagate in the absence of electric and magnetic fields?
It has been established that light or other forms of electromagnetic radiation needs electric and magnetic fields in order to propagate. What would happen if it were possible to shield an area from ...

Understanding sources (charge and current densities) in Jefimenko Equations
Let's consider the two Jefimenko Equations:
$$E(r,t) = \frac{1}{4πϵ_0}∭_V[\frac{e_{r-r'}}{|r-r'|^2} ρ(r',t_r' )+ \frac{1}{c} \frac{e_{r-r'}}{|r-r'|} \frac{∂ρ(r',t_r')}{∂t} - \frac{1}{c^2} \frac{1}{|...

How would I calculate the minimum and maximum wavelength of the Bremsstrahlung released by an electron as it goes through a magnetic field?
Say, I have an electron gun and ground below it (with a potential difference of U) and two coils side by side between them producing a relatively homogenous magnetic field B. If I shoot an electron ...

Direction of magnetic field, current carrying conductor and its motion
In Fleming's left hand rule, we can see that if current is in direction of middle finger and magnetic field in the direction of fore finger, the thrust must act on the direction of the thumb. These ...

Same behaviour of EM radiation at the polarisation grid and at the double slit?
In a diffraction grating, the EM radiation is polarised after passing through the grating, i.e. the electric and magnetic field components are aligned by the grating bars, one component parallel, the ...

How can electric wave and magnetic waves have any angle between them?
I have been taught that the electromagnetic length of a wave is a geometrical property that can be measured in units of length, while its amplitude (both the electric and magnetic) is not a ...
