Hanna curve

Hanna curve - a curve defining magnetic parameters of an inductor. [1]

An example of Hanna curve for a gapped inductor

Hanna curves help in finding optimum working conditions (maximum energy stored in an air gap) for an inductor. Several parameters are taken into account, including: magnetic field or flux density level, size of an air gap, physical dimensions of the magnetic core, number of turns of the winding, etc.[2]
