Even an ideal inductor has capacitances associated with it and you will see 1/2.L.i^2 energy redistrubted into 1/2.C.V^2 energy. If there is little or no resistance you will see oscillations as energy is dissipated over longer than a resonance cycle - in the form of electromagnetic radiation if no other means exists.

The size and shape of an inductor can affect its energy storage capacity by changing the strength of its magnetic field. A larger and more tightly coiled inductor will have a stronger magnetic field, allowing it to store more energy compared to a smaller and loosely coiled inductor. The standard explanation is that the magnetic field stores the ...

PCB inductor design and circuit performance rely heavily on precise inductance estimation. Incorrect inductance levels can cause unintended circuit behavior, impacting an electrical device''s reliability and efficacy. This is why precise calculation of inductance is so important: Inductance (L) = (μr x μ₀ x Ax N²) / l.

The energy, stored within this magnetic field, is released back into the circuit when the current ceases. The energy stored in an inductor can be quantified by the formula ( W = frac {1} {2} L I^ {2} ), where ( W ) is the energy in joules, ( L ) is the inductance in henries, and ( I ) is the current in amperes.
