(MMF) balance and will spew a large amount of leakage flux that has
the potential for heating the floor or walls of a cabinet. It is sometimes
used because it requires less iron than a three-leg core design. The
three-leg design has cancelling fluxes from the conductors and has a
minimum leakage flux. The small cost difference is good insurance
against field problems.
