This video explain how to increase the energystoring capacity of Inductors and coupled inductor model transformer used in flyback amps by introducing air gap... This …
An inductor''s energy can be discharged quickly, generating a very high voltage, as E = LΔI/ΔT or the EMF generated is proportional to the change in current divided by the change in time. The voltage is high for a large inductor as the current goes from maximum to zero in a fraction of a second.

The theoretical basis for energy storage in inductors is founded on the principles of electromagnetism, particularly Faraday''s law of electromagnetic induction, which states that a changing magnetic field induces an electromotive force (EMF) in a nearby conductor. An inductor exploits this induced EMF to generate a magnetic field, thereby ...
Energy storage capability of an inductor depends on both its inductance and the square of the current passing through it. In AC circuits, inductors can temporarily store and release energy, causing phase shifts between voltage and current. Review Questions ...
Inductors Explained
Inductor Energy Storage • Both capacitors and inductors are energy storage devices • They do not dissipate energy like a resistor, but store and return it to the circuit depending on applied currents and voltages • In the capacitor, energy is stored in the electric field between the plates • In the inductor, energy is stored in the ...

Mathematically, energy stored in an inductor is expressed as Where w is the energy stored in the inductor, L is the inductance and i is the current passing through the …
And with this the answer to your question is hopefully obvious. The energy stored in an inductor is stored in its associated magnetic field. Just like an electric field a magnetic field has an energy density, but given by the equation: $$ …
