Question

What is the necessary condition on EM field for vanishing Poynting vector?

Answer 1

Heya...

What is the necessary condition on EM field for vanishing Poynting vector..?

Answer:- Necessary condition on electromagnetic ( EM) field for vanishing Poynthing vector are ___

Vector must be moving in the propagation direction for radiation pressure so that the EM can be measured easily...

But if the EM is static then he vector can also be zero...

Thank you

Answer 2

$\huge\underline\mathfrak\purple{Solution}$

The necessary condition is that the vector is in the direction of propagation and also radiation pressure should be present but for static it can be zero

Thanks!!! ✨❤
