I think that inductive loads also put out a small pulse of energy as the waveform gets near zero this is not as you say a harmonic as such just a low level pulse I hope this isright. Sorry to labour the point im just trying to get it in my head
No, you are wrong. A pure inductance ( no such thing) would simply have current lagging 90 degrees from the voltage and consume no power. However all inductors have some resistance so the current is lagging by less than 90 degrees and some power is consumed.
No low level pulses, no harmonics.
