Magnetic Flux Density - an overview | ScienceDirect Topics operating magnetic flux density is the parameter that determines the loss in the magnetic core. Similarly, current density in the windings determines the loss in the windings. When the current density is increased, cross-sectional area of the windings is reduced and hence, the volume and in turn copper weight are reduced.
