Transformers are also constrained in their performance by
the magnetic flux limitations of the core. For ferromagnetic
core transformers, we must be mindful of the saturation
limits of the core. Remember that ferromagnetic materials
cannot support infinite magnetic flux densities: they tend
to "saturate" at a certain level (dictated by the material
and core dimensions), meaning that further increases in
magnetic field force (mmf) do not result in proportional
increases in magnetic field flux (Φ).
