The Electric Field Of An EM Wave

Posted by R R Riepen on January 26, 2000 03:28:19 UTC

An oscillating charge in an antenna creates an electromagnetic wave that continues to propagate after the power to the antenna is turned off.

But this EM wave itself consists of oscillating E and B fields. If the E field of the EM wave is oscillating in the Z direction then even after the E field strength goes to zero wouldn't the already created E field continue to spatially propagate in the z direction?

Can a distant charged particle feel the effect of the E field created by the time varying B field in the EM wave?
