The first key difference between a capacitor and inductor is energy storage. Both devices have the capability to store energy, however, the way they go about doing so is different. A capacitor stores electrostatic energy within an electric field, whereas an inductor stores magnetic energy within a magnetic field.
$begingroup$ If we assume the shield is non-conductive high permeability magnetic material which only has a caveat for the wire turns you''ll get the same inductance with much fewer turns in the shielded structure (assuming the dimensions and materials are the same except a piece of the outer shell is missing in the non-shielded version). You …

In a weak energy environment, the output power of a miniature piezoelectric energy harvester is typically less than 10μW. Due to the weak diode current, the rectifier diode of traditional power management circuit in micro-power energy harvester has a high on-resistance and large power consumption, causing a low charging power. In this paper, an …

Because the current flowing through the inductor cannot change instantaneously, using an inductor for energy storage provides a steady output current from the power supply. In addition, the inductor acts as a current-ripple filter. Let''s consider a quick example of how an inductor stores energy in an SMPS. Closing the switch for a …

Homopolar inductor machine (HIM) has been widely applied in the field of flywheel energy storage system (FESS). However, conventional HIM suffers from the low power and torque density due to its unipolar air-gap flux density. To solve this problem, a novel multi-unit out-rotor HIM (MOHIM) with bipolar air-gap flux density is proposed. First, the structure and …
Energy storage is not the main point of the inductor. You need one, otherwise the instantaneous charging current would be enormous. They are used in switch mode power supplies to allow one to hand off energy to the other. And keep the transfer of energy with low losses. Without the inductor the efficiency would be shit for high power supplies.
The formula for energy storage in an inductor reinforces the relationship between inductance, current, and energy, and makes it quantifiable.
