An electromagnetic wave& having equation,& \overset{→}{E} = {E}_{0}\cos ( kz - \omegat ) \overset{^}{i}~travels in vacuum along -direction. A rectangular loop is to be kept such that at~, displacement current may flow through its area. Which of the following is the correct orientation?
Options
- A
- B
- C
- DAll three configurations are possible.
Correct answer
C.
Step-by-step solution
We know that electromagnetic waves have electric as well as magnetic vectors which are vibrating& perpendicular to each other and these two vectors are also vibrating& perpendicular to the direction of the motion.
Here, the direction of displacement current is the same as the direction of motion of wave which is along& \overset{^}{i} [ x\text{-axis} ]. So, area vector should also be along \overset{^}{i},~i.e., plane.
