( Electrical engineering : Circuits , Electrical power )
In practice, energy is dissipated due both to the resistance of the windings (known
as copper loss), and to magnetic effects primarily attributable to the core (known as iron loss).
The inductance will not significantly change due to larger wire, so you can use the
same number of turns as you have now with heavier wire and it will reduce the copper loss.
Copper loss is loss occurring in a conductor due to the flow of current, when conductors were
traditionally made of copper.
