The typical values of leakage factor are approximately from:. Calculate the EMF induced in it. Testbook Edu Solutions Pvt. Our Apps. Let us imagine that an EM Wave, passes an area A perpendicular to the X-axis along which the wave travels. While passing through A, in infinitesimal time dt , the wave travels a distance dx. The above equation gives us the energy per unit time, per unit area at any given instant of time, which is called as Poynting vector.
