How to Calculate Poynting Vector Magnitude?
Poynting Vector Magnitude calculator uses Poynting Vector = 1/2*((Dipole Current*Wavenumber*Source Distance)/(4*pi))^2*Intrinsic Impedance*(sin(Polar Angle))^2 to calculate the Poynting Vector, Poynting Vector Magnitude represents the rate of energy flow per unit area in an electromagnetic field, calculated as the cross product of the electric and magnetic fields, measured in watts per square meter. Poynting Vector is denoted by S_{r} symbol.
How to calculate Poynting Vector Magnitude using this online calculator? To use this online calculator for Poynting Vector Magnitude, enter Dipole Current (I_{d}), Wavenumber (k), Source Distance (d), Intrinsic Impedance (η) & Polar Angle (θ) and hit the calculate button. Here is how the Poynting Vector Magnitude calculation can be explained with given input values -> 12437.29 = 1/2*((23.4*5.1*6.4)/(4*pi))^2*9.3*(sin(45))^2.
