Transformer and inductor design — Switchcraft· When the secondary of the transformer is loaded, the increased current causes a voltage drop in the winding resistance. This causes the flux density in the core to be slightly reduced, as there is less magnetizing voltage available. Ideally however the flux density in the core should remain constant regardless of load. Impedance transformation
