The Electromagnetic Wave of a Coil

AI Thread Summary
The electromagnetic wave generated by a coil travels indefinitely but diminishes in strength with distance. Its propagation is influenced by factors such as the current flowing through the coil, the coil's diameter, and the number of turns. Increasing the current in the coil will enhance the strength of the emitted waves. Biot-Savart's law can provide further insights into the behavior of these electromagnetic fields. Understanding these principles is essential for applications involving coils and electromagnetic waves.

Hello everybody, First excuse me for my English.

Could someone please explain how far the electromagnetic wave of a coil travels?
Does it depend on the current flowing in the coil? The coil diameter? The coil's number of turns?
What will happen to the waves if we increase the current of a coil by two times?

Thanks in advance,
SMT

According to classical theory it spreads without limit but weakens with distance.Try googling Biot and Savarts law.

Thank you very much!
 
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...
