Electric and magnetic fields can store energy and its density relates to the strength of the fields within a given volume. This (volumetric) energy density is given by where E is the electric field, B is the magnetic field, and ε and µ are the permittivity and permeability of the surroundings respectively. The SI unit is the joule per cubic metre. In ideal (linear and nondispersive) substances, the energy density is
