Answer:
The magnetic field strength, the energy density, and the power flow per unit area are , and 13.18 W/m².
Explanation:
Given that,
Electromagnetic wave strength E= 70.5 V/m
(I). We need to calculate the magnetic field strength
Using formula of Electromagnetic wave strength
(II). We need to calculate the energy density
Using formula of energy density
(III). We need to calculate the power flow per unit area
Using formula of poynting vector
Put the value into the formula
Hence, The magnetic field strength, the energy density, and the power flow per unit area are , and 13.18 W/m².
