Energy Density is described as the amount of energy stored in a region or system per unit volume. Electric and magnetic fields can store energy. Energy density is denoted by using the letter U
Regarding electromagnetic waves, both magnetic and electric field are equally involved in contributing to energy density. Therefore, the formula of energy density is the sum of the energy density of electric and magnetic field.
formula:
U = E² * (ϵ₀ / 2) + B² / (μ₀ * 2)
where:
U - energy density
E - electric field
B - magnetic field
ϵ₀ - vacuum permittivity, ϵ₀ ≈ 8.8541 * 10^(-12) F/m
μ₀ - vacuum permeability, μ₀ ≈ 4π * 10^(-7) H/m
*This is a universal app that work for both iPhone and iPad.
