Calculating Magnetic Flux Density in Transformer/Inductor ...· Note that energy density goes as B^2 / (2*mu), so the energy storage in ferrite is abysmal (almost nil, because mu > 1000 for most), and most filter chokes are wound on gapped, or distributed gap (e.g., powdered iron) materials. An air core choke has the highest energy density, because it won't saturate and because mu = mu_0, as low as it can go.
