Question

In an electromagnetic wave, the direction of the
magnetic induction B ➝ is
(a) parallel to the electric field E ➝
(b) perpendicular to the electric field E ➝
(c) antiparallel to the Poynting vector S ➝
(d) random

Answer 1

Answer:

ans:B

that is perpendicular to electric field

Explanation:

as electromagnetic waves are formed due to interconversion of electric field to magnetic and vice versa

also the direction of propagation of wave, electric field and magnetic field are perpendicular to each other
