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.

Thread 'Reflections at the source point of a transmission line'

I was using the Smith chart to determine the input impedance of a transmission line that has a reflection from the load. One can do this if one knows the characteristic impedance Zo, the degree of mismatch of the load ZL and the length of the transmission line in wavelengths. However, my question is: Consider the input impedance of a wave which appears back at the source after reflection from the load and has traveled for some fraction of a wavelength. The impedance of this wave as it...
