the "500 ft spool of wire" as an inductor has some simplicity and

(copper being expensive these days, it's not as cheap as other means)

I think the 500ft spools of #12 THHN stranded copper measure around 9mH.
The mostly complete spool that I use with my potential transformers
measures 8.5mH.


9mH = 3.4 ohms at 60 Hz, 2.8 @ 50

1 spool = 35 Amps at 120 V, 60 Hz
