SUMMARY
The units for electric energy density and magnetic energy density are both confirmed to be J/m³. The magnetic energy density is calculated using the formula μ(mag) = B²/(2μ₀), while the electric energy density is derived from μ(electric) = (1/2)(ε₀)(E²). Dimensional analysis demonstrates that both expressions yield equivalent units, affirming the consistency of energy density measurements in electromagnetic theory.
