inductance
Let an agent explain inductance, relay definitions, units, formulas and applications from physics and electrical engineering sources, describe the named forms, relay safety on inductive spikes, and distinguish inductance from capacitance, resistance, impedance and magnetic flux.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain inductance, relay definitions, units, formulas and applications from physics and electrical engineering sources, describe the named forms, relay safety on inductive spikes, and distinguish inductance from capacitance, resistance, impedance and magnetic flux.
The property of an electrical conductor or circuit by which a change in current induces an electromotive force, measured in henries, arising because current creates a magnetic field whose changes induce voltage according to Faraday s law, including self-inductance within a single coil and mutual inductance between coupled coils, as in transformers, and in power engineering leakage inductance, the part of flux not linking both windings, and short-circuit inductance used in transformer and machine testing; inductors store energy in magnetic fields and are used in filters, power supplies and wireless charging. Opening circuits with large inductance can cause dangerous voltage spikes.
What it is for: Describing magnetic energy storage and induction in circuits.
It can be explain definition and units; relay formulas and behaviour; describe named forms; relay safety.
Distinguishing features
Magnetic energy storage
Opposes current change
Self and mutual forms
Frequency-dependent reactance
What it looks like
Not a physical object; embodied in coils, inductors and transformers.
Physical character
SI unit: henry unit - H, weber per ampere
energy stored: L I squared over 2 formula
Faraday s law of induction: 1831 year
How it is recognised
Opposition to current change via magnetic induction
Self-inductance, mutual inductance, short-circuit inductance, leakage inductance
Capacitance stores electric field energy; resistance dissipates energy; impedance combines effects in AC; magnetic flux is the field quantity
