Answer :
The average intensity of an electromagnetic wave with a peak magnetic field strength of B is I = cB^2/2µo
Define the intensity of an EM wave?
The energy that crosses per second per unit area perpendicular to the electromagnetic wave's direction is what is referred to as the wave's intensity.
Any wave's energy is proportional to its amplitude squared. Thus, the intensity of electromagnetic waves can be written as
I = cε0E^2/2
where
I represents the average intensity of the EM wave in W/m^2.
E represents the strongest possible electric field created by a continuous sinusoidal wave
c is the speed of light
ε0 is the permitivitty of free space
If B is the strongest possible magnetic field and µo is the permeability of free space, then the average intensity of an electromagnetic wave, I, can also be represented in terms of the strength of the magnetic field using the relationships
B = E/c, and
ε0 = 1/µo c^2
The highest magnetic field strength B can also be used to express this as,
I = cB^2/2µo
Hence, the average intensity of an electromagnetic wave with a peak magnetic field strength of B is I = cB^2/2µo
