Leading and Lagging AC Power

To the Ineffable All,
It takes energy to increase the magnetic field. For instance, a permanent magnetic already has a magnetic field about it, and the energy to establish that field was supplied when it was manufactured. To increase that magnetic field even more is going to require additional energy. An ideal inductor is usually defined as having no coil resistance.

Thanks Adam, I see what your saying.
Academically, It's common to ignore some factors in order to simplify things for the student trying to learn the basics.
Such as conductor resistance, impedance, or efficiency in a circuit.
I believe your ideal inductor could be designed perfectly, and and be 100% efficient, but It would still effect the power factor because of its inductance.
Naturally, wasted energy and power factor are not the same thing.
