Question

Philoid · Accepted Answer

i) the electromagnetic wave is propagating in z direction; the direction of electric field is along x axis and for magnetic field it is along y axis

The integration along the rectangular loop 1234 is given by,

This is the value of integral .

ii) For calculating , consider a small strip of area ds = h dz

iii)

Given that:

Substituting the value obtained in part i and ii we get,

iv) Consider the loop 1234 in the plane y-z,

Now consider the strip of area h.ds in the rectangle 1234.

Given:

Where, I = conduction current

For vacuum I = 0
