Electromagnetics (Numerical Problems)
1. If the earth receives 2 cal/min-cm2 solar energy from sun, calculate the amplitudes of electric
and magnetic field of radiation?
2. Assuming that all the energy from a 1000 W lamp is radiated uniformly, calculate the average
value of the intensity of electric field of radiation at a distance of 2 m from the lamp.
3. If the magnitude of electric field vector in a plane wave is 377 V/m, determine the magnitude
of magnetic field vector for a plane wave in free space.
4. A lamp radiates 500 W power uniformly in all directions. Calculate the electric and magnetic
field intensities at 1 m distance from the lamp.
