The maximum electric field in a plane electromagnetic wave is `600 N C^-1`. The wave is going in the x-direction and the electric field is in the y- direction. Find the maximum magnetic field in the wave and its direction.

Text Solution

Verified by Experts

Solution:
We have `(B_0)=(E_0/c)=(600 N(C^-1)/3 xx (10^8)m (s^-1)) = 2 xx (10^-6)T.`
` As (vec E)(vec B) and the direction of propagation are mutually`
` perpendicular, (vecB) should be along the z-direction.`
