UExcel Physics: Study Guide & Test Prep D) All In The Electric Field. The energy per unit volume in an electromagnetic wave is Answer A) all in the magnetic field. 233, the energy stored per unit volume in an electromagnetic wave is given by (331) Since, , for an electromagnetic wave, and , the above expression yields (332) or (333) It is clear, from the above, that half the energy in an electromagnetic wave is carried by the electric field, and the other half is carried by the magnetic field. The energy per unit volume in an EM wave is. In general, the energy per unit volume in an electric field is given by: energy density in electric field= 2 1 ϵ 0 E 2.
