This theoretical unit of inductance represents an exceptionally massive resistance to changes in electrical current. In practical electronics, inductance is usually measured in microhenrys or millihenrys. A component rated at one million henrys would require an impossibly massive coil of wire and magnetic core.
Heard on the job
You would need a coil the size of a building to get a megahenry of inductance.
