inductor does not store energy

How does an Inductor "store" energy?

A static electric and / or magnetic field does not transport energy but due to the configuration of charges and / or currents. In the case of an inductor, work is done to establish the magnetic field (due to the current through the inductor) and the energy is stored there, not delivered to electromagnetic radiation (''real'' photons which would ...

Inductance | Textbook | CircuitBread

The broader definition of inductance – the ability to store energy in a magnetic field – does apply, but this is not what is meant by "pin inductance" or "lead inductance.". What is actually meant is the imaginary part of the impedance of the pin or lead – i.e., the reactance – expressed as an equivalent inductance.

Power loss in a capacitor vs inductor

Also, for the same occupancy / volume, a capacitor can store more energy than an inductor. But, you could also factor in the method of putting energy into the capacitor or inductor. For instance, if you charged a capacitor from a voltage source, you would immediately lose 50% of the energy (a pulse of "infinite" current would also flow …

Introduction to Inductors

You can get a greater magnetic field using a core than without one. 1. AIR CORE INDUCTORS: Like the name suggests, this kind of inductor has no core – the core material is air! Since air has a relatively low permeability, the inductance of air core inductors is quite low – rarely above 5uH.
