Question

In electromagnetic wave propagation why electric and magnetic fields are in same phase

Answer 1

$\huge\blue{Hi,}$

Maxwell added a second source of magnetic fields in his correction: a changing electric field (or flux), which would induce a magnetic field even in the absence of an electrical current. ... Electromagnetic Waves: Electric (red) and magnetic (blue) waves propagate in phase sinusoidally, and perpendicularly to one another.

Hope this answer may help you!

Thanks N Regards
