Do Electric Fields Always Create Magnetic Fields?

AI Thread Summary
When a voltage is applied to two plates, an electric field is generated between them. Initially, during the charging phase, a magnetic field is present due to the movement of charges. Once the plates reach a steady state with a constant DC voltage, the magnetic field disappears. However, if an alternating current (AC) is applied, the electric field varies over time, which according to Maxwell's equations, will continuously generate a magnetic field. Thus, electric fields do not always create magnetic fields; it depends on the nature of the current applied.

Hello, if I put two plates one in front of the other and apply a voltage I read that an electric field creates, but shouldn't also exist a magnetic field since there are moving charges ?

thanks

I assume you apply a constant DC voltage. During the short period of time in which the plates are "charging up", there is a magnetic field. After the plates become fully charged and are in a steady state, there is no magnetic field.
 
if you will apply AC then ,of course the electric field is time varying.which according to maxwell eqn will generate a magnetic field.

This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...
Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'
Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
